I met a guy who ended up stranded in the snow for days because of a broken leg with mountaineering equipment but no means to light a fire (ie, no wood). He ended up putting the snow in a plastic, watertight bag and putting the bag inside his sleeping bag, where it would melt based on the radiant heat he lost to the interior of the sleeping bag. Wasn’t a lot of water, but it was enough to survive until help arrived.
@@gcewing It increases the risk, but it's not directly lowering his core temperature as it would if he was swallowing it. Given that he's inside an insulated bag, there's plenty of time the waste heat from his body to restore the warmth inside the sleeping bag; especially if the bag is between his clothes and the bag-lining, and not under his clothes, directly on his skin.
@@gcewingIt’s far better than eating it. The energy loss from the body heat given off in the sleeping bag isn’t that different with or without a bag of snow. Directly ingesting it is going to have a far greater effect of heat energy pulled from the body.
You should really prioritize food last. So: Water, Shelter, Food. Unless you're in an extreme environment (freezing cold etc.) .. then Shelter moves to the number 1 spot. The average human can survive 3 weeks w/o food (3 days without water) so while of course it's important and needed for survival .. it's not as important as shelter from the elements and whatever critters are out there.
Yea its shelter first, not just in cold. Though in cold it follows the rule of 3 :( 3 min without breath, 3 hrs without shelter, 3 days without water, 3 wks without food.) BUT In jungle you need to get off the floor and cover from rain. Even in deciduous forest you need protection. On a tropical island you'll probably be ok on the beach but not if a hurricane happens, but you head inland to look for water and you'll need shelter first inland. Every environment has predators, insects etc. You can go 3 days without water, you may not be able to go that long without shelter.
as long, as you are not in a situation, in wich you can find a way out in a time, you are capable of walking (depends on how much energy you have), shelter is nr one.
Tampons aren't good for bullet wounds, but they *are* great firestarters, especially if you can coat them in candle wax or a bit of cooking oil before lighting them. You can also use them as a stage 1 filter for purifying water (it will remove particulate matter, like sand and gravel, but NOT microbes or bacteria, so the water will still need to be boiled to make it safe to drink). If you fluff them up a bit, they can fit pretty snugly in the opening of a plastic water bottle. Tampons have a place in survival kits, but their best uses aren't first aid.
No, I saw it in a cartoon once. When you’re in a falling house, wait until the last second, then step out the front door on to the ground as the house smashes behind you.
In 1974 I survived a 5 story industrial elevator freefall, I have never heard anyone even close to understanding what really happens, your suddenly weightless, you lose perception, no time to react
You're right that people don't get it. Gravity is really fast. I was working about 12 feet up on a scaffolding that collapsed. I reached up to hit a nail, next thing I know I was sitting on the ground. You don't have enough time to even think about jumping.
As a Canadian I was definitely taught that eating snow will hasten hypothermia. I was also taught that if you are in an avalanche to blow on the snow so it melts a bit and you can then use the direction the water droplet travels to indicate which way is down (so moving in the opposite direction is up and therefore out of the snow). You can also do the opposite with bubbles if you get stuck under the ice. Though, as disorienting as being plunged under the ice would be, knowing which way is up is the least of your worries. The shock is almost as bad as the hypothermia and a lot of people die from involuntarily breathing in water. Being Canadian is fun I swear. I love living in a country that hurts my face for 5 months. 😅 🇨🇦☃️
Come to Australia mate, Canada sounds like heaven. Nice easy temps to deal with, if it's cold put on more clothes or build a fire. hardly any nasty critters, and the ones you have are big enough to spot and avoid if you have a couple brain cells. Try avoiding our crazy critters in 48°c.
@@shaneebz5292 Don't be fooled, Canada Geese are the frozen norths counterpart to Drop Bears. Lurking around every corner and just when you think they've left for the winter the fuckers come charging out of a bush.
There is a story of Polish-Canadian girl being stuck for three days in Tatra high mountains during winter due to the avalanche risk and snow storm… they found her healthy casually waiting for the rescue team thanks to her school training and extra equipment.
One thing to note. If you're stuck in the desert and you have water such as a jug or canteen, drink it. Don't save it for later. Your body needs that water inside you not inside a container. And you're actively dehydrating. It's not going to help you later if you're dead. And plenty of people have died of dehydration with water in a container.
As an explanation for the last part, dehydration can seriously impair cognitive function, so people simply don't think about drinking their water if they're seriously dehydrated
Not quite the best idea... if you have a large amount of water and you are already hydrated and you drink all that water you will waste some of it on the ground.
Another one i heard growing up: hiding under an overpass if a tornado hits is worse than just being in a field because of the wind tunnel effect. Best thing to do is get out of the car and lie down flat in a ditch.
@@Jude30as opposed to getting stabbed with a 2x4 going 150mph. There’s no truly safe place in a tornado, but the safest place is anywhere that won’t have debris hitting you horizontally by making your horizontal presence as slim as possible. Be it in a ditch, a bathtub, a basement, the shore of a pond/river, or even just laying down on the ground.
@@Atlassian. it’s not really disputed. When you break it down the winds are still hitting you and debris can do the same… couple that with the fact that winds can speed up under bridges and it’s just not a good idea to be under one.
My grandfather (born 1907) worked in a grocery store as a teenager. He was unpacking boxes of menstrual pads and asked his boss what they were for. His boss told him they were for polishing cars. So Grandpa took home a box and did just that. Obviously, tampons are for areas of the car that are harder to reach or need a little more scrubbing power. My great-grandfather had to explain what pads were really for so grandpa wouldn’t use them on the car again.
You can usually tell if a large colony of bats live in a cave because they often leave a deep layer of guano on the cave floor, which is definitely not a place I wanted to seek shelter in.
Physics says it would work but you'd have to jump at the exact same force at the correct time. The one problem is any ceiling above would hit you as hard as the floor would have. Science sucks lol
Canadian here, 100% was taught IN SCHOOL like 25 years ago (early grade school) never to eat snow for hydration because of the exact same reasons listed here. Ill still take a bite once in a while just for joy though.
It is correct that ice can cool your core temperature it is beyond ludicrous to say it will dehydrate you. With the exception of perhaps the tampon advice this video has told people to do the wrong thing in every circumstance.
Depends on your acclimation, the temperature, melting method, and density of the snow IMHO. Melting compacted, heavy, wet, snow is easy with heat from your hands or another external heat source. For example the sunshine through your windshield. There are many scenarios in which using snow as a water source can save your life.
Another famous myth is drinking from cacti in the desert. *Some* cacti are safe, but others contain oxalic acid (including some of the famous barrel cacti that are supposedly safe), and you can badly burn your mouth and esophagus trying to drink from them.
One recommendation for the falling elevator is actually bend your knees rather than lie down completely. Firstly if the lift is falling from a height that gives you enough time to lie down then you are probably dead anyway. Secondly, as long as your knees are loose, you will crumple achieve the lying down without the delay. Locked knees - the panic reaction - will break your legs, but loose knees will crumple. The sudden sitdown will hurt your backside, but that is, for most people, well padded and so you'll be alive. Trust me on this one - I've personally done it. I know it is NOT impossible for a lift to fall down a lift shaft. The various things reduce the odds a lot, but it is not 0%. And I'm not talking a theme park ride either. However, I'd not recommend it - still hurts, just not as much as broken legs or dying.
I was going to call bullshit since we've all seen pictures of snowy tropical beaches, but the guy holding me in his basement says that's actually just limestone or coral sand. Outside sounds wild.
@@Soundbrigade My sister was in a job interview and they saw that she was bilingual, as she also speaks Spanish. The interviewer then asked if she speaks any other languages but it turns out she speaks the two-language variant of bilingual.
As someone who has been in these survival situations: its all down to luck, my example will be water. I live in Canada and especially in the spring certain areas get the purest glacial meltwater. But that doesn't mean much if there's a dead moose a few hundred meter upstream. It's one tip for high temps, like desert or just a brutal summer, do not conserve you're water. It is so easy to get dehydrated without realizing it cause your all like I'll just take a sip here and there. NO, if you are thirsty drink. People have been found dead in the desert with water in their canteen. In the end it loops back to luck. You either find water or don't, the water is good or it isn't. Though I have heard of a good story about a guy found by search and rescue next to a river with dehydration so bad it damaged his kidneys. When they asked him why he didn't just drink the river water he said "it might have given me parasites." Sooo I mean it really is all situational.
Many years ago, a buddy and I were backpacking high in the Cascades in Oregon, along a crystal clear creek. We drank the water right out of the stream without boiling it. It was clear, cold and tasted absolutely wonderful. When we got home we had diarrhea for three days. We were so sick.
The story of the "dead moose" (for us Europeans more the "dead deer") in the stream I often heard from my parents when we drank from creeks, I always countered with: "And why should a dead dear lie exactly in that stream and that for a long period of time?" They most probably die anywhere else than that specific creek and get eaten within days, so I don't see any problem with that. But cooking the water first won't be harmful anyways.
With that food thing- there's also plenty of things humans can only eat after processing properly, but animals can eat raw- like acorns. And, there are several things humans can eat that most other animals can't too- like onions/ garlic & most species of mint.
i’ve been on the street homeless in the winter and when we ran out of water i’d store some in bottles and use the heat that would accumulate in our tent (shocking it got extremely HOT in there) to melt it before drinking. i’m so thankful that i had a decent grasp on common sense and enough of what i had previously considered “trivia” - it definitely saved me and the both of us many times.
I had an ex girlfriend whoos dad was an elevator repair man. His pay rate was very surprising when i found out. He had an unbelievable amount of knowledge in regard to his field..and for this and due to the importance of saftey and having good people in his position, he was very well compensated. He took his job very seriously. Trust that your elevator has been maintained by someone who had thier shit together, and is beyond safe. They make $100 an hour.. and they earn that because theres a lot to know to keep people safe, and they ensure that everything is in proper working order. He was a very smart guy (and a giant at 6-8). Knowing that people like him are responsible for elevator safety and how seriously they take thier job alleviates any worry i once had.
@@paulhaynes8045 he wasn't just tall, he was massive. I'm surprised he could fit in one, lol. I heard a story that he got into a fight with another driver, who had a friend with him. He only had his daughter with him, but beat he both thier asses despite one of them hitting him in the head with a crowbar while standing on his hood ( probably couldn't reach him otherwise haha). I didn't catch how old she was at the time, but that's the story I got from her, and he confirmed it. Super chill guy.. if it happened like that he had no choice. No temper at all..
Yeah he probably wasn't making 100 an hour... unless he for some reason got a bunch of pay bumps that nobody else gets. Elevator repair says that they make less than 100k a year, so stop your BS.
@thomgizziz I repair elevators and my wage is $130 an hour. Which is just above standard rate these days so stop inserting yourself into people's comments with nothing to say except arguing. I pity your life. I hope you find something ro smile about even just on e rhis year.
@@dramatticdevon4741 Thanks dude. I saw that dude's comment and just rolled my eyes..His name is Darell, and as stated he absolutely makes 💯 an hour. Lol. Thanks for having my back.
If you have a. the skill to trap/kill it without expending more energy than you would gain from it, and b. some equipment to cook it. Not fun to have food-borne diseases and/or parasites while having access to remedies, but it's so much worse when you do not.
Taking a rock to a lot of animals is a good way to get killed. Humans aren't particularly strong, nor particularly fast. Please don't actually try this. Many animals are extremely dangerous if in distress. Some deer for example can kick at 700PSI, and if you get hurt, whether minorly, or severely without any medical supplies, or medical knowledge on how to treat your wounds infection will become a massive risk. @@Carewolf
I love the fact that the thumbnail for this video, about jumping in an elevator, is also at the beginning of the video. Soooo many others would place it at the end. Thank you! Now, I'll watch the entire video from start to finish because I highly respect that ❤
Actually, putting the fire at the entrance of the cave is extremely fangerous because the air from outside pushes the smoke back in. Cou terintuivel, you should build the fire at the back of the cave as the smoke will travel along the ceiling, and go out.
Cave shelter pro-tip: if seeking shelter in a cave or under an overhang during a lightning storm, DO NOT sit directly in the mouth of the cave; a lightning strike on the rock face could arc and jump across the space from the roof of the opening to the floor. You don't want to be sitting there.
Actually the newest research suggests that lighting a fire in the back of the cage is more favorable than in the front because it creates a circular air motion drawing fresh air in.
If there was ever a time to practice cock pushups, that's it. Not only can you say you literally drilled it into the ground, but you technically followed the correct safety advice too, as well as Tenacious D. It's a win-win-win.
Hmm interesting, I referenced a Tenacious D joke involving male parts and certain exercises, which seems to have gotten my comment auto-filtered, yet I now get notifications for replies to the original comment even with mine not showing... I'll let people derive the clearly hilarious joke I made from the information here, on the basis that I doubt Simon and his team would waste their time unblocking it...they want to keep the genius of the hilarious comment hidden for their own evil schemes and not share it, I understand.
As a former athletic trainer I can say that tampons can work to control nose bleeds. I wouldn’t use it for bullet wounds precisely because it just becomes soggy. In a nose the nostril would limit how much it expands but that’s about it. Don’t use them for actual wounds.
Leaving the tampon in the wrapper and using it together with a bandage to provide additional pressure on the wound is the only way I can really see a tampon being useful in first aid, doing the same thing as a rolled-up bandage. Or, like, keep proper pressure bandages in your first aid kit. My first aid instructors have always been very insistent that you never put anything in or take anything out of the patient. That will almost always make things worse. Your job is to buy the patient time for the paramedics to arrive, not cure them.
I always figured surviving a freefalling elevator would be similar to just free falling. While standing cage your head with your arms, make sure every joint in the legs, arms, and back are at least slightly bent so they don't lock out or bend the wrong way. Click your feet together so they more precisely impact at the same time, stand on the balls of your feet so the heels don't impact first, and lean forward and slightly off to one side. The lean is so that when you do impact you don't land backwards and increase the cances of a spinal injury or head injury as only your hands are back there to shield your head, and the leaning to the side prevents falling directly forward where the elbows will hit the ground and get pushed out of the way exposing your face to a high impact. Landing to the side instead presses the lean side arm into the head allowing it to act as a cushion. Your arm and jaw might break, but your chances of a fatal head injury are less
06:38 That one is only toxic when the ibotenic acid has not been decarboxylated, cooking will make it non-toxic. You will however discover why we have depictions of flying reindeer.
Maybe part of why the guy survived since he still had a car available. Having the ability to go into shelter that can maintain some heat for a period of time (although the internal temperature will level out with ambient at night, that said a car can become a green house trapping heat if it is sunny) you may be able to heat the snow enough to melt it.
Not to mention, snow is an insulator so it'll help keep your body heat inside the car rather than letting it all escape. It's not a great insulator but there's a reason people survived in igloos for thousands of years.
Although tampons aren't good for a first aid kit, maxi pads are. I was in the Nordic Ski Patrol back in the late 70's and I was told to buy maxi pads to fill out my kit instead of standard gauze bandages. You could get a box of the former for the same price of one of the latter. Back then they didn't have "wings" or any other things so they were basically just sterile gauze and worked quite well as a bandage. And with regards to melting snow, you're better off keeping a small amount of water unfrozen put it in a pot and drop the snow in the pot. I did a bit of winter mountaineering back then as well, and I kept a bota with water under my clothes to keep if liquid. If you try to melt just snow in a pot, it takes a lot of fuel, assuming you have a camping stove, because as Simon noted, it's mostly air. Melting it in the water first, means you use a lot less fuel. And keep your boots at the bottom of your sleeping bag when you go to bed. That way, they don't freeze.
That is terrible advice. Maxi pads are going to leave behind fibers whose removal from a wound is screaming torture. Buying them instead of proper gauze is planning to fail or sociopathy.
no, they were never sterile. so this was an odd thing to teach Then again, my local red cross instructor taught us to "check for spine injury" by lifting a persons leg and hitting the sole of their foot/shoe to see if it hurt (Not joking, he taught us that as part of a first aid course..... I was too timid to say anything, but I hope that guy never actually "helps" somebody with an injured spine
One more thing to add to the elevator part. There are buffers in the pit for that reason (hydraulic, spring or polyurethane, depending on the nominal speed of the elevator, which is kinda tied to the travel height of it). Not sure if this was meant by the "crumple zones" as thats not really a thing at least on elevators i work on. Falling on buffers isn't going to be a pleasant thing, don't get me wrong, but its also not gonna be like dropping on solid concrete either. Air working as a buffer is also kinda debatable as in elevator shafts that can have problems with piston effect, they tend to add air relief holes to negate that. I guess technically you might have some air cushioning the fall but not really enough to make a difference.
A note on snow. It takes more than twice a much energy to melt snow as it does to raise it to body temperature. Plus what it takes to raise the temperature of the snow to the melting point. Let's say the snow is at 0 F (-18 C). Per gram it takes - 9 cal to heat the ice to 0 C - 80 cal to melt the ice - 36 cal to heat the water to body temperature Total: 125 cal Vs: Just 36 cal to heat water from 0 C.
More of this kind of video, maybe a sequal about undderated effective survival tips, like using sos pads and the square batteries can be extremely effective at lighting even damp wood, or how covering your head with a hat hood etc is actually better than leaving it exposed in a hot desert environment despite it seeming like wearing nothing or as little as possible would be better for staying cool (i don't remember how this works )
This whole video was kind of dumb. Like how often do people find caves (rarely)? How often are people stranded or lost and there is a cave nearby (almost never)? How often do elevators freefall? (Never)
@rubiconnn well the frequency of caves depends on the terrain, and survival knowledge by nature is something you learn but hopefully never have to use, the elevator one I'll give you but it's probably a common misconception among older people, after all the myth was popular enough to appear early on on mythbusters. But it's still interesting, I wasn't previously aware of the crush zone or that lying flat was better, sure I'll likely never need to apply that knowledge but this is ultimately entertainment ans at least personally I was entertained.
the covering up in hot environments works because the sun is a deadly lazer, and clothes are very effective at blocking UV light not getting severe sunburns is better than "staying cool"
@@PeterParker-qi7coLouis is a man's name. Undoubtedly the OP meant to say "Lois Lane" the name of the woman in the Superman series. Dude, that was an easy one.
On the topic of eating snow: *never* do this. Even if you were to assume (as Simon did for the sake of his excellent explanation) that the snow is uncontaminated by animal droppings or man-made chemicals, well, the problem is that you would really have no way of knowing for sure. Even snow that looks pristine and perfectly white could be contaminated in some way. Unless this is extremely deep snow, it would be difficult to gather any appreciable amount without also inadvertently scraping up some of the soil and dirt under the snow as well... and we all know that soil is chock-full of various types of bacteria, most of whom aren't pathogenic, but some of which are, and in some cases, lethally pathogenic like clostridium botulinum. In the absolute worst case scenario, if you have no choice, try to at least boil the water you get from melting snow before drinking it. This won't save you from chemical contaminants, but it may help protect you somewhat against the risk of contracting typhoid fever from bacteria in the snow. Ideally, though, if you must forage for drinking water far from civilisation, you would start doing so _before_ your current supply of water runs out entirely. Of course, there's the problem (as Simon mentioned) that snow is mostly air, so trying to obtain drinking water from snow is a _very_ inefficient process which is further compounded by the fact you'll have to do this whilst trying to avoid freezing to death along the way. Hopefully you have a buddy or two to help divide the labour a bit. So what's the best way to survive one of these extreme situations? Don't get into an extreme survival situation in the first place. Check the weather before you go out, and if you have any reason to doubt your safety, don't go. Above all, prepare accordingly whenever you venture out far beyond civilisation, and make sure that your friends and family know where you are going, so that if you don't return at the expected time, they'll be able to notify the authorities to send someone to find and rescue you if you get into trouble. Stay safe out there!
Idk man, I live in Ohio & we've been eating sno-cones we made ourselves for years. & idk what you consider extremely deep snow, but an easy 6 inches is common, and you won't get anywhere near the ground here. When you say extremely deep in thinking over 6-8 feet. That's not as common.
Honestly, last bit of advice might be the worst advice. Everyone has their own lives. Its like being afraid of skydiving bevause there's always a chance your main amd back up chutes fail. Or never climbing everest bevause you're afraid to die. The point of learning to survive extreme situations is so that you can take part in activities, amd be ready for the worst possibilities.Humanity would never have come to where we are today if everyone followed your advice
@@hteetyit’s more like not climbing Everest because there will be a blizzard or a storm or something. He ain’t saying never do any extreme sports but make sure that it probably won’t be in dangerous conditions and letting people know where you’re going isn’t exactly a bad idea in case something does happen. It isn’t bad advice to attempt to make dangerous activities less dangerous.
It doesn't have to be super deep. As long as the snow is undisturbed (e.g. not compacted as a result of something walking over it, and with no visible discoloration) and you can scoop it without scooping up dirt (which is usually pretty easy in snowy areas) you can readily collect pristine snow, which is effectively rainwater (which in turn is basically distilled water mixed with ambient air). As long as the snow is outwardly pristine, contamination only becomes an issue if the air is contaminated, in which case you're breathing in contaminants anyway.
As a first responder, the breakdown of stopping life-threatening bleeds is extremely thorough and well-explained. And I loved the emphasis on identifying what will kill someone faster, bleeding or infection from unsterile packing material. People overestimate how much blood is in the human body. An average sized human being can bleed out from a severe bleed within minutes, and even if the bleeding is stopped, it’s likely the person has already gone into shock, which in its own right is maybe one of the biggest medical concepts that is misunderstood and needs its own debunking video.
First priority in a survival situation if you are able to breathe and are not bleeding profusely is to maintain your core body temperature. That means finding a way to stay warm in cold environments and cool in hot environments. Hypothermia or Hyperthermia will end you within minutes to hours in extreme conditions unless you can insulate yourself from them somehow. Get out of the wind and into the sun if possible in cold environments, then find a way to insulate yourself from the ground. Leaves and branches work well if you find yourself below tree line. Make a mat with them first. Do not exert yourself to the point you sweat. If you must exert yourself heavily, remove clothing so it doesnt get wet, and don it again as soon as the task is complete. Build a fire if possible. Dry out any wet clothing. Make a lean-too or dig a snow cave if possible. Find a hollow tree or a V between some rocks. Squat on your feet and huddle for warmth if you cant insulate your butt from the ground. Minimize contact with cold things. Desert survival is similar. Avoid hot things like direct sunlight and the ground or rocks that have been heated by it. Find or make shade, and only exert yourself between dusk and dawn. In either case, stay put unless you know exactly where you are, and how to to navigate back to civilization, and have the strength and equipment and supplies necessary to do so. Carry an EPIRB or a phone with satellite distress calling capabilities like the Iphone 14 and later models. Most of all, don not enter the wilderness unless you are prepared to spend at least a couple of days sleeping rough, and can summon help if you get hurt or lost. Carry a map and compass and know how to use them.
Yup. The Otis Safety elevator. It's what made high-rise buildings practical. Otis famously demonstrated his invention at The 1853 Wold's Fair. It's still one of the most successful publicity stunts in history. From Wikipedia: "At the New York Crystal Palace, Otis amazed a crowd when he ordered the only rope holding the platform on which he was standing to be cut.[2] The rope was severed by an axeman, and the platform fell only a few inches before coming to a halt.[5] The safety locking mechanism had worked, and people gained greater willingness to ride in traction elevators; these elevators quickly became the type in most common usage and helped make present-day skyscrapers possible." Talk about confidence in your own invention!@@DavidLLambertmobile
@@DavidLLambertmobile Otis was also the the man that invented the first practical elevator emergency brake. I would love to be able to go back in time and watch his demonstration of the invention before that crowd. Chopping away at the cable holding him up, only to drop a few inches as the brake kicked in automatically.
3:12. First concern is shelter. Hypothermia can kill in hours. Then water. You can survive 3 days without water. Food is actually relatively minimal concern. You can last about 3 months without food. Itll suck, but you'll live.
Hours if you're lucky. If you're wet, especially in water, it can be a matter of a few minutes. And often times it's not the hypothermia, it's the stupid stuff you do because you're brain is too cold to operate properly. The survival without water can vary. My grandfather lasted roughly 2 weeks, but he was inside with properly maintained room temperature and was going to die regardless. I personally managed nearly a month on basically no food. IIIRC, it was like a cup of yogurt a day due to a bad stomach infection. I felt fine through out, so I'm wagering that something closer to 3 months would be possible, although it would come with numerous longterm health impacts. This is why it's generally body temperature before water. (And it absolutely has to be clean, diarrhea can be absolutely fatal if you're already low on drinking water) And water before food.
@@satgurs incorrect. You can still freeze to death when it's 50 Fahrenheit. Unless it's 98.6 degrees outside you're losing body heat to the environment. Shelter is always first. Thanks for playing though. Better luck next time.
I think the mistake of using tampons for bullet wounds is also in part people forgetting that certain words in one language don't mean the same in another. Tampon is a french word for buffer and if the label of a medical gauze package includes French it will also include the word tampon. Likely American soldiers heard and say the word a lot around the French in WW1 then when they got back to the USA and heard the word used to describe feminine hygiene products they where like "did you know those are used for wounds in battle?"
Thank you so much for bringing up these myths. One I didn’t know personally is the eating snow one. One I’ve been trying to dispel is the tampon one. I’m an avid shooter and trained in field trauma, and this is so pervasive.
Astonishingly persistent, too. I've been shouted down for disagreeing with it, despite mine and my instructors credentials being *significantly* better (and including actual evidence) than some dumb mook who barely passed medic school and never saw an actual GSW in his entire three years of service pushing the myth.
Yeah, there was a video a while back of Russian conscripts being told by an instructor to ask their girlfriends to send them tampons for improvised medical kits for the purpose of plugging bullet wounds if they couldn't get a real one....
Most elevators nowadays aren't even cable lifts, They're hydraulic columns.(think an old car antenna) Even if there was a failure and the elevator started to "fall", the hydraulic column would fall so slowly that nothing would happen. They've been phasing out cable lifts for quite a few years now I think.
Hydraulic elevators have a maximum height though. They haven’t been phasing out cable(traction) lifts at all. In fact they are still the go to for high rise applications. They’ve been moving away from steel cables in some applications, using high strength rubber belts with steel reinforcement within them. But if you have a high rise thats 500ft tall, you’d need to dig a 500ft hole in the ground for your piston. Not to mention the massive tank you’d need to hold all of the oil. Plus hydraulic elevators are just too slow. Going from floor 1 to floor 60 would take you several minutes. Cable suspended traction cars are capable of going upwards of 1600 ft/min and beyond. Until we master the art of levitation, traction elevators will always be prominent in buildings taller than 50-60 feet. Source: I’m a licensed elevator mechanic.
4:36 smoke inhalation is probably obvious, me immediately flashes back to Clarkson's "revolutionary" camp fire in Top Gear's Australia special where he built the camp fire around their campsite. 🤣
I remember learning in medic training to pack a wound with gauze then wrapping it, and taking a timed test to do that under a certain amount of time. honestly, one of the most fun tests in medic training.
In around 1981 I was on a school field trip to Grand Coulee Dam. We were in the dam in an elevator going up. This was back when you could still go inside the dam on tours. The elevator stopped and dropped maybe about 10 feet, then went up again, then stopped and dropped 10 feet or so again, then started going up and then stopped and the door wouldn't open. We were stuck in that elevator for 45 minutes or so. One kid was saying he would just jump right before the elevator hit the bottom. The rest of us told him it doesn't work that way. The elevator was stuck at the top of the dam, so it would have been a long fall. Later on a fireman told me about the safety backups in an elevator and that were were safer than it seemed. But I think about that day every time I'm in an elevator.
If you have an environment where you can keep warm, such as the buried car of the man who was trapped for two months, you can put the snow into a vessel to naturally melt. Once you have enough, that would be safe. However, remember opening your "igloo" to get the snow will lose you some of the built up heat and the snow itself will cool the environment as it melts. Life is a balance. 🙂
Elevator horror stories are pretty rare nowadays, for the reasons you cite, but if you want to be freaked out read old newspapers from a hundred years or so ago about early elevator technology and it's like mass carnage. Scary stuff.
The incident in the Empire state building, where a lift fell dozens of stories comes to mind. It was completely and utterly obliterated, including its human occupants... But that was like a century or so ago, as you mentioned there were no failsafes yet back then.
With any luck we will have figured out public transportation in the future and look back at today's car accident statistics with horror about how we allowed that to continue for so long.
@@JaredLS10 And I was briefed by former SF medics during my training that tampons are a bad idea for exactly the reasons he listed. Experimental evidence also supports their use for GSW being a horrendous idea. Your Corpsman friend was, like many medics who confuse six months of training for being on par with medical school and research experience, wrong.
Quick clot is a last ditch effort if pressure doesn't work though. Have used it a few times on patients in the field. Understandable why they don't like it.
4:10 I saw a video saying it’s actually worse to build the campfire at the entrance. Best to have it in the end as it will create a less toxic air flow. Still a terrible idea without a hole in the roof however
Yeah was about to comment the same, putting it in the middle or the back makes hot air/smoke to rise while cold air comes in from the entrance. Blocking off the entrance would just pump smoke into the cave, especially if the fire is too big or the entrance small.
There are a lot of considerations for whether to even use a cave as a shelter. The slope of the floor and ceiling, the direction the cave-mouth opens toward, the caves general shape and depth, and whether the cave is used by bats. If the cave is used by bats, waking them up isn't the worst thing. The worst thing is that they poop on the floor of the cave, and that poop attracts a ridiculous number of insects. Now, we'll assume the cave isn't used by bats at all. The important considerations are what direction does the mouth face, the depth of the cave, and the slope of the floor. The direction the cave faces will impact winds around the cave, which will determine how air circulates in the cave. Along with the cave's shape and dimensions, and the local geography and flora. Air flow relies on smooth surfaces, and in caves, surfaces are generally anything but smooth. These differences cause eddying in the flow, which serves as a barrier. That barrier will trap gasses produced by the fire, such as CO and CO2, and suffocate you in your sleep. Especially if the floor where you are is lower than the entrance of the cave. If you are using a cave as a shelter, putting the fire at the entrance allows the wind to pull the smoke across it and away from the people. You want to sleep near your fire for warmth. You need to know how to place a fire. Use no more than the first two or three meters of a cave, build a fire-pit, use rocks as heat-sinks and reflectors, and keep your fire small. Any fire meant for survival should always be small, just enough to keep you warm, and maybe heat some water or cook something. You aren't heating the entire cave. And you don't want to spend hours looking for fuel for your fire.
Simon's videos should be regarded as entertainment, not reliable information. He tends to put out stuff that is not well edited. His mistakes are sometimes left in the videos.
There should be a disclaimer for the don’t eat snow… You shouldn’t eat snow if you’re stationary and trying to stay warm, then you should be drinking water, preferably boiled and still relatively hot…. That’s a super important distinction. But if you’re active and staying warm through movement and work, eat as much snow as you’d like, BECAUSE it’ll cool your body down and the goal is to avoid sweating at all cost when you’re working or being active out in the cold.
I thought the elevators that were hoisted by a cable (the other type has a hydraulic post that is below the enclosure) lifted the thing by a leaf spring. If the cable is separated or sheared, and there's no tension pulling up on the spring, it relaxes and the ends protrude (extend) past the car and catch in the rails. Therefore, the elevator cannot freefall. You stay there and wait for the car to be lowered, or they get you out through the door in the top/ceiling of the car.
But mostly, because there's an astonishingly persistent myth that they're useful for gunshot wounds, and that appeals to the type of idiots who buy survival kits.
I remember when in Boy Scouts, some younger scouts from a different patrol group grabbed rocks from the river to make a fire ring. No one realized their stupidity until a rock fractured and sent shards flying. Luckily, no one got hurt, but damn! The Scout Master was pissed!!!
*Regarding eating snow:* Surely, there's a break-even point... There's a considerable difference between the energy required to melt solid water near 0°C and -273°C.
I can't remember the term for it, but there is an extremely large (relatively) amount of energy required for a substance to actually change states, so the last little bit before actually turning into liquid would take alot more energy to warm up than any of the other "degrees" it had already warmed, likely more than all of them put together. Not to mention your body may not need to warm the water anymore once it is liquid, but it will still be losing heat to that water until it reaches your body temperature.
Cause I'm a nerd, tried to find the actual amount of energy needed for phase transition and found this: "Using the equation for a change in temperature and the value for water (334 kJ/kg), we find that Q=mLf=(1.0kg)(334kJ/kg)=334kJ is the energy to melt a kilogram of ice. This is a lot of energy as it represents the same amount of energy needed to raise the temperature of 1 kg of liquid water from 0ºC to 79.8ºC" That said it's not instantaneous, and the same energy spread over time has different impacts, and there's a whole bunch kf complicating factors (snow n someone's stomach and a block of ice in a lab aren't exactly identical), but the gist is the same, it's going to draw a lot of heat from your body and if you're in an environment where snow is the only water source you probably need to keep as warm as possible. Source for that quote if anyone wants to double check, I only had time to skim the page in honesty: phys.libretexts.org/Bookshelves/University_Physics/Physics_(Boundless)/13%3A_Heat_and_Heat_Transfer/13.3%3A_Phase_Change_and_Latent_Heat
@@ruledtrendy5066That's right. The energy required to change a substance's state is called latent heat, and energy that changes a substance's temperature is called sensible heat.
I don’t know if my son watched this video, but we were in an elevator (which he hates anyway) and as we were stepping out of it he told me that if it fell we shouldn’t jump. 😂 He is on the ASD spectrum, so it’s not unusual for him to pop off with things that seem to come out of nowhere. Anyway, he explained it pretty well. I’m impressed! 💜
i'm a survivalist and wilderness guide from finland and i see zero problems with eating snow if you know what you're doing. i do it often an IT DOES NOT DEHYDRATE YOU like simon said. it will cool you down but that is no problem when moving and many times beneficial to stop you from sweating.
Canadian here. I'm a big guy and generate a lot of heat when I'm trudging through snow even in negative 30. The cooling effect of snow helps big time and certainly does not dehydrate you.
@@sebastiantru4702 exactly. there has been stupendous amounts of videos saying "ACTUALLY you should never eat snow" and that it´s a myth you can eat snow if you´re thirsty. it´s just the reverse of the reverse. the "gotchas" went 360. of course if you´re hypothermic or even just cold in general it´s not good to eat snow and you should melt (or even boil) the snow when possible. that way you get way more water in you if you´re thirsty. but if i´m dying of thirst i´d still eat snow no matter how cold i was if i have no access to melting the snow other ways. only in this situation "it depends" but the "fact" that you should NEVER EVER eat snow is a billion percent FALSE.
Food tip. Rub the juice or the thing on your skin. A patch test to check for allergies keeps it there for two days. If you know you gonna be stuck for a longer time, start early and start with rubbing it on, if you have no responce, keep it there for an hour, if the next day you still have no responce take it a step further. Also not fullproof but it is a bit safer then ingesting immediately.
Absolutely. Also, there's plenty of water in the desert if you know when and where to look. The WHEN is the most important part of any choice you make in an arid environment.
@@Mercurio-Morat-Goes-Bughunting exactly. Sometimes a piece of plastic comes in handy to get it as well. If you dont carry a small plastic bag to collect trash on your walks, it's a good safety net in an emergency for water.
@@id10t98 It doesn't need to be hard work, either - which can also be the difference between life and death in an arid environment. If the plant isn't poisonous, you can seal the bag around some clean foliage and water will collect at the bottom of the bag in the evening. No need to sweat finding stones and digging pits. The trick is to stay in the shade during the day and get things done at night.
You really shouldn't have to pack a wound (Chapter 4) unless it's in the crotch area or armpits. The best thing you could learn to do is how to apply a tourniquet or fashion one from a shirt, belt or bandana and a stick. In the case of gut wounds use a clean dry pressure dressing and do not try to stuff intestines back inside a abdominal cavity. Chest wounds you would like to have a seal dressing (can make one with a ziploc bag and tape) while monitoring for pneumothorax. I could go on and on about battlefield care
For years I've argued that lying flat in a falling elevator was your best bet, glad to hear the experts (there are experts in elevator fall physics?!) back me up.
The elevator advice seems bad. 1) there is 0% chance that you are going to be able to lie on the floor of a falling elevator. You don't have time to react and you're going to be floating off the floor, probably up against the ceiling for most of the journey 2) You don't want your legs to act like a crumple zone? Just take the impact directly to your vital organs and head? 🤔
@@CleverAccountName303 If you're able to stand at all, standing with knees and hips lightly bent seems the best choice. They are our bodies' built in shock absorbers, even if they won't be able to do enough to save us in this scenario.
The whole snow thing isn't without precedence. I read a book about the Antarctic explorer Sir Ernest Shackleton. He said when they were holed up in their tents in minus 50 degree temperatures, what they did was to pack snow as tightly as they could into their drinking flasks/canteens. Then they would put them in the bottom of their sleeping bags, the radiant heat from their bodies was enough to melt the snow but not enough for them to suffer hypothermia. This was just enough for them to keep going. 'Endurance' if your interested, a very good read.
I just watched a similar video a few days ago that said not to build the fire next to the cave entrance, because the wind/airflow will push the smoke into the cave. They said cavemen always built their fires in the back or middle of the cave, so that the air would come in and wrap around taking the smoke out with it. I'm no expert though, so idk which video is correct.
Ive survived an elevator fall. The air bag thing is real and i felt it. Happened so fast i barely had time to think. I was a kid playing around with an elevator having a game with friends racing each other to the bottom and after like the 4th time it happened and i just remember feeling butterflies in my tummy and then a feeling like standing on an inflatable matress after you let the air out. The doors opened and the floor was a good few feet misaligned with the ground floor. I had to jump down. And i looked up at my friend who was coming down the stairs (we where racing) and he has like "How did you get so fast?". I hate elevators to this day.
Another elevator survival tip: Do not attempt to leave an elevator that is stuck/malfunctioning/misaligned; call for help and/or use the emergency phone inside the elevator to call for help and wait until firefighters or some other personnel arrive and only exit when they say it's safe. If you're inside an elevator that's stuck and it suddenly drops again, you're probably going to be okay because of all the other safety systems. But if you're attempting to climb out and it sudden drops, you get cut in half. You might feel silly just standing there waiting for possibly hours when the door is open and you could easily climb out, but it's not worth the risk.
@sykes1024 Yeah. Wish someone told me that as a kid. I do remember my parents mentioning something like that after the fact, though, and then everyone saying, l was so lucky i didn't get cut in half. You know how it goes with all the neighbors talking about something big that just happened 😅.
It wasn't an air bag. It was some sort of an emergency brake that stopped the elevator. Elevator shafts are not airtight, so such a pocket would not stopped elevator completely, just slightly slowed down the final impact, it would not be a few feet high (air compresses quite effectively) and finally once the door was open, even if the shaft has been airtight (which it isn't), the "air bag" would leave through the door and the elevator would have fallen to the ground.
I live in very clean environment with not much pollutants. Don't eat snow. If you throw a snowball, made from freshly fallen snow on to a hot sauna fireplace, it'll smell bad. You can instantly tell there is something iffy. I've teached my kids to not eat snow by this, and by melting a bucketful of snow. It has all sorts of.... Stuff in it. Little particles of different colors etc.
@@Ksoism so, actually not a very clean environment. Microplastics are everywhere these days, even the Antarctic, but visible particles and also smoke particles aren't a thing of clean environments.
The problem with elevators, is they typically fall UP, not down. The counter-weight is heavier than the car and contents. To fall down, an elevator would need to lose both braking and cables. To fall up, you just need to lose brakes.
I knew all of these already except for the tampon one. I'm surprised to think that people have thought of using them for such a thing. Great video with good information, wish it was longer with more scenarios.
One morning, my car was absolutely *buried* under the snow...I got enough off to open the driver side door (yes, I DID clear it properly before driving off!) and dang - it was *warm* in there! Proof that igloos are a good idea.
Regards to the elevator I don't think everybody knows that fact that they are traveling at the same exact speed that the elevator is dropping. So the elevator and the human are traveling at the same rate accelerating at the same time prior to that. Ergo lay flat just like gravitron carnival rides
The elevator falls first. So you are not going to be touching the ground in a free fall situation. Even if you are only one centimeter off the floor, you have no control to maneuver yourself. The elevator will start to slow down very slightly from the air pressure buildup, which gives you about 1/10000 of a second to collect yourself and get in the "right" position. Good luck Bad advice about spreading out the impact anyway. We are not a balloon, we have more important areas in our bodies than other areas. You don't want your legs to act like a crumple zone? Just take the impact directly to your vital organs and head? 🤔
@@johndinner4418 Ribs pulverisation vs broken spine and broken ribs. Great choice, isnt it? At least laying on spine will preserve your face somewhat for identification.
The "stabbing a stick into the ground to mark the shadow's movement to find North" is because you actually can't immediately tell which way is North based on the sun alone. - For most people, the sun will have a prominent Northern or Southern "lean" in relation to how far away you are from the equator. This lean can become very extreme as you enter Winter or Summer. - With that in mind, for most of the day you will only be able to discern that the sun is up. If you naively think "it's before noon, so the sun should be in the East" or "It's afternoon, then the sun should be in the West" then you _will_ very quickly make yourself _more_ lost as what you thought was East was actually South/South-East _(which is one of the many reasons why you are more likely to survive if lost if you simply stay where you are)._ - Even when the sun is rising or setting, that still won't get you due-East or due-West but South-East or South-West _(if you live in the Northern Hemisphere)._ However, when you mark how much the shadow moves over time, you aren't tracking the sun's location but the sun's _movement._ That is how you can get a much more accurate understanding of East/West by using shadows instead of the sun directly. If it's night time, look for the Big Dipper. The last star in its handle is Polaris - the "Northern Star," named such because no matter what time of the year you're in, that star will *_always_* point you North - assuming you're on the Northern Hemisphere. For those in the Southern Hemisphere there's "Sigma Octanis" that always points you South, but apparently it's pretty dim and somewhat hard to spot by the naked eye? As for discerning if food is venomous, simply have it bite/sting you and see if you react. _(sorry, had to reference the venon v. poison meme, lol)_ To discern if it's poisonous, there's actually a surprisingly long series of checks that can take a few days to fully rule out if a food is poisonous. The steps start with "crush between your fingers; if they start tingling after a few minutes, it's very likely poisonous" before putting some of the juice on your lips, then your tongue until you eventually eat *_the smallest portion possible._* Then you just slowly work your way up to an actually useful amount of food. It takes a few days because there's a waiting period between each step, with the later steps having a waiting period of 1-2 days _each._ Of course, you would need to source a clean water supply first because a very *_very_* common symptom of poison in one's food (especially when it's at such small amounts) is food poisoning. . . . . .hence the bloody name "food poisoning," lol. And once that happens, you can survive assuming you don't end up dehydrating yourself from your body's. . ."reactions." With the tampons one: There is such a thing as "pack the wound," which is where I think the myth originated from. The issue is that there's some prereqs to if a wound should be packed that I'm not qualified enough to state with absolute certainty. Ultimately your goal in such a situation is to stop the bleeding - even if it means losing the limb. You can survive from losing too much of a limb from having a tourniquet too high up, but you can't survive from losing too much blood. I also want to take this opputunity to state: DO NOT REMOVE THE GAUZE/TOWEL/WHATEVER IF IT'S "FILLED." Yes, dressings need to be changed to prevent infection, but at that moment an infection is the _least_ of your worries. The whole reason why gauze is shaped that way with the notably large holes is so that the blood can have an area to adhere to through surface tension before clotting instead of simply running down the body clearing the way for more blood. When you remove the gauze, you're essentially ripping off whatever clotting has formed, putting the victim right back onto Square One. Instead, you simply keep piling it on until the bleeding has stopped. In fact, in serious wounds it's common to tourniquet the limb - if possible - while also piling on the dressings. Ultimately what keeps blood from large wounds from clotting is your own blood pressure. Stop the blood pressure and the blood is much less likely to simply push any micro-clots out of the way. Only after the bleeding stops do you slowly loosen the tourniquet. Also, a limb can survive a surprising amount of time without oxygen. The concept that the body needs a constant supply is yet another half-truth. It's the _brain_ that needs a near constant supply. However, a limb can go without blood supply for close to 6 hours. If you've ever woken up with zero control over one of your arms for a good few minutes, that's exactly what happened.
The shadow line technique for finding north is commonly useful when calibrating a compass. If you want your compass to point true north (and account for magnetic drift) then the shortest shadow of the day, cast by a vertical object, points north along a horizontal surface in the northern hemisphere and south in the southern hemisphere. I've used this on more than one occasion and it's also solidly reliable for determining midday, local time (as opposed to the time of the local timezone) if you're using sunsights for navigation. In the absence of functional safety systems, jumping in a falling elevator has zero effect on outcome. Even at the moment of impact, you assume the elevator's speed - the speed imparted by the jump, then, by the time you hit the deck, gravity has undone the speed change you gained from your jump and you hit the stationary floor of the elevator at the same speed as the elevator was travelling at on impact - which is exactly the same as if you'd just stood there. Caves are not the healthiest place to seek shelter. Never light a fire inside a cave. You'll burn up the oxygen - assuming that something flammable hasn't been gathering there for the past 20000 years and, well, that's one way to go out with a bang! Cave-ins are a feature of mudstone caves, generally not sandstone. If you hear a hiss or see a ghost, leave. A hiss indicates a sediment trickle which, in turn, indicates something's broken and you may not want to be around when the chickens come home to roost. Ghosts, and other locality-specific visual hallucinations, are a visual response to infrasound and infrasound, in any structure (including buildings as well as caves), is indicative of gradual structural collapse and typical of metastable structures which might hold together for years then collapse without warning. In short, if you're not a geologist, don't go deep enough into a cave to need a torch, lamp, or flame. Dehydration by snow consumption makes no sense. Snow cools you down. You don't sweat unless you reach a certain internal temperature no matter how much energy you burn. So, unless snow can elevate your body temperature it can't kill you by dehydration. Hypothermia? Yes. Definitely. Dehydration? Not in this species! Otherwise, eating icy-poles would not be a thing in the summer because it wouldn't feel refreshing or drop your core temperature - which is something that can be a problem in the cold. So, your biggest problem in a cold environment is lack of heat and if it's that cold and you can't find warmth, it won't matter either way.
@@randomname4726 I take my vow of abstinence from faith very seriously. Why should I believe in anything when belief is the basis of all deception and error? That said, can you explain how a drop in core body temperature results in dehydration given that loss of fluid due to sweating is core temperature dependent, not a function of power...? Here's a fun experiment - and I've done this a lot just as par for the course so I already know how it ends. Work up a sweat in the summer. Don't do anything extreme. You don't want to get to the point where you stop sweating or it will stuff up your experiment. Now, go indoors, take your temperature, and dry off. As soon as you've stopped sweating, take your temperature, again, then eat four icy-poles or, alternatively, drop some ice-cubes in the blender and scoff down the icy mix. Do you start sweating again? When you subsequently take your temperature, has your body temperature gone up or down? I'll take reproducible experimental evidence over a piece of paper any day...no matter how official.
Trees can give shelter, but *light no fire* close to one - without checking for snow load on branches above. Collapsing half-slushy, warmed snow will snuff a fire, wet the burnables, AND cool you off.
Oh man, if you don't have more of these videos, please make more!!! This was so interesting especially about the snow, had no idea that would be so detrimental. You might just save lives with this video lol
As a lift engineer myself they are very safe the brake can only lift if there is power to it, in a power cut the brake wont be able to pull the relay in that tells the control panel to lift the brake in the first place so dont fear, and 1 of those steel cables is strong enough to hold the lift on its own plus the device under or on top of the lift that is also a brake will pull in if the lift travels fast then the speed it is set to. Lifts are safer than driving a car
In critical emergencies involving gunshot wounds, the pressure really is the critical element. The pressure against the wound is what triggers the body's natural clotting response. There's a lot of complex mechanisms involved, but the punchline is this: if you can maintain constant pressure for long enough the wound will close itself up, albeit in a weak manner initially and is extremely vulnerable to reopening. But if you are in an extreme situation and you have to move the wounded person in question, it's much more survivable if you're able to maintain pressure on the wound. The longer you can maintain pressure, the better.
You can use your body to melt snow and drink it, just depends on the situation. I did it on a survival course I took in the winter. With all the heat I was generating over the two days from all the wood I was cutting down and lugging around on my own to build my shelter, and then later smoke signal, and also to supply for a fire, I was burning a lot of calories and generating a ton of heat. So much so that I eventually had to remove my toque and walk around with my jacket open. Temps weren't super cold though, about -5 to 0 degrees celsius. It would probably be a different story in -30 or -40 temps as I know some folks had to deal with. Point is, in my situation, packing snow in to my water canteen then putting it under my shirt to melt it wasn't exposing me to hypothermia as I was already boiling up from the 2 days straight of tree cutting and moving them. Of course, a fire to melt the snow and ice is always best, but you can use your body heat IF you aren't at risk from hypothermia by doing so. You just gotta be the guy doing all the work to work up all that extra heat. ;) That all said I did break the rule and eat a bit of clean snow, but that was more for relief from all the heat I was working up. I melted as much of it as possible to drink later.
I'm struggling with a few of the conclusions: First the advice to better not eat anything other animals eat and just stick to drinking water. I know from personal experience that indeed you can survive on water only but it has a significant impact on your energy and wellbeing. Considering that you're lost in the wilderness this is far from ideal and can create a life threatening situation. I have also observed monkeys eating certain legumes and followed suit which turned out to be fine. In a survival situation this could potentially save your life. I'd argue it would be worth trying a small amount first and determine how your body responds. Being able to find something to eat seems crucial to me for survival. Second is the advice to not eat snow for hydration. Although I understand the risks involved, it seems clear to me that the example given of the man who survived two months while eating snow proofs that it can be a life saver. Without water a human cannot survive much longer than a week, so him surviving two months on snow proofs that he got hydrated while overcoming the downsides. Because of this I doubt the conclusion that the energy expenditure caused severe dehydration. I suspect that taking small amounts at a time would allow your body to recover without serious complications. it seems a risk worth taking over not surviving from dehydration.
The people who say you can survive x amount of days without food often seem to forget that this only applies if you aren't moving. If you are moving, because, for example, you're lost in the wilderness and are trying to find your way out of the wilderness, well then you won't survive much more than a week without food, and you'll be forced to slow down considerably after two or three days at most.
@@legrandliseurtri7495 Well, you'd be better of staying still than blundering around the wilderness in random directions, because that's more predictable for search parties.
He didn't actually spend 2 months stuck in his car. He was discovered on February 17th 2012. On the 28th of December, he drove a few metres. He also celebrated New Year's Day with energy drinks and vodka. And in mid January he attempted to walk to the nearest supermarket but gave up after falling 3 times in 10 metres. And he did melt the snow before drinking it.
Regarding being lost in the woods, learn about the local flora and fauna, before you go anywhere, dress for the weather and carry the things you really need, including the means to protect and help yourself.
Back in the 90s, my mom's cousin was in an elevator that malfunctioned horribly... it repeatedly went to the 3rd floor and then went slamming to the bottom, then back up to the 3rd floor before crashing down again. This happened multiple times before he was rescued. He survived (although with pretty significant injuries) and uhhhhhh got quite a bit of settlement money out of that incident.
On the last one: That only applies if you're staying in one place and not doing anything. If you're walking and active, you generate body heat quickly. You can easily wind up sweating. Cold is ome thing. Wet and cold is dangerous. Sweating is bad. Movies & video games where people get their feet wet in the cold... Yeah, in real life, you don't get your feet wet in the cold unless it's necessary. Anyway, the point is that in reality, thermal management may make eating snow necessary. To keep your body heat down to minimize sweating. How much energy does it actually take anyway? I've always wanted to the math and check if these ideas are valid. I've been told not to drink very cold water when working in the heat because it takes too much energy to for the body to warm it up. I've been told similar myths about it taking too much energy to digest food. What I do know is legit it that you can't survive long without water. Apparently, you have at most 2 days, maybe 3 if you're very lucky. Then cramps and stuff. You're alive, but not functional enough to get the water you need. Without actual hard evidence I have a hard time buying into this idea that it takes too much energy to equalize temperatures. If anything, the hazard is hypothermia if you're not active. If you're active, "cotton kills." Because it absorbs water and holds it. When you stop and cool-down, you're in dangerger without a fire or warm-up.
Survival tip: get an audio book with advice from your grandmother. Play it constantly and follow the instructions... yes including such things as "Don't trust men with moustaches"
Idk where I learned this (probably on tv) but if you have 2 plastic bags (water tight) and you need to drink snow, you can pee in one of the bags and use the other to collect snow. The warmth from the pee will melt the snow and you can drink.
I wonder about the fire in the cave thing. If you are seeking shelter from rain and/or wind you'd have a harder time keeping the fire going if it's near the entrance of the cave. Also, if the fire is in the entrance of the cave and you are behind it (deeper in the cave), any fresh air coming from outside would have to pass over the fire before reaching you, possibly being contaminated by smoke and carbon monoxide in the process. With that in mind, maybe it would be best to make the fire a few meters from the cave entrance and for you to stay between the fire and the cave entrance, so that you'd be closer to the fresh air coming from outside. But then, I don't know what would happen to the toxic gases generated by the fire. My thinking is that since they are heated up by the fire, they would rise, so even if they have to leave the cave through that same entrance they would be closer to the ceiling, while cold air coming from outside would be closer to the floor. That's all pure speculation on my part, and I'm definitely not a specialist in the area.
I heard that for the fire in a cave it’s actually the opposite because heat in the entrance would make the part of the smoke that gets inside to accumulate instead of escaping. It’s an interesting point about the heat expansion of the rocks though. Seems like it’s a gamble either way.

I met a guy who ended up stranded in the snow for days because of a broken leg with mountaineering equipment but no means to light a fire (ie, no wood). He ended up putting the snow in a plastic, watertight bag and putting the bag inside his sleeping bag, where it would melt based on the radiant heat he lost to the interior of the sleeping bag. Wasn’t a lot of water, but it was enough to survive until help arrived.
The energy to melt the snow still came from his body, though, so not much better than just eating it, I think.
@@gcewing It increases the risk, but it's not directly lowering his core temperature as it would if he was swallowing it. Given that he's inside an insulated bag, there's plenty of time the waste heat from his body to restore the warmth inside the sleeping bag; especially if the bag is between his clothes and the bag-lining, and not under his clothes, directly on his skin.
Just so long as he skipped the yellow snow.
It's information for American viewers.
@@gcewingIt’s far better than eating it. The energy loss from the body heat given off in the sleeping bag isn’t that different with or without a bag of snow. Directly ingesting it is going to have a far greater effect of heat energy pulled from the body.
You should really prioritize food last. So: Water, Shelter, Food. Unless you're in an extreme environment (freezing cold etc.) .. then Shelter moves to the number 1 spot. The average human can survive 3 weeks w/o food (3 days without water) so while of course it's important and needed for survival .. it's not as important as shelter from the elements and whatever critters are out there.
shelter ( which obviously build it near water if you can ) first, then water, and food.
Please. Remember. Whats. First.
Protection (shelter). Rescue. Water. Food. -Bear Grylls
Yea its shelter first, not just in cold. Though in cold it follows the rule of 3 :( 3 min without breath, 3 hrs without shelter, 3 days without water, 3 wks without food.)
BUT
In jungle you need to get off the floor and cover from rain. Even in deciduous forest you need protection. On a tropical island you'll probably be ok on the beach but not if a hurricane happens, but you head inland to look for water and you'll need shelter first inland. Every environment has predators, insects etc. You can go 3 days without water, you may not be able to go that long without shelter.
as long, as you are not in a situation, in wich you can find a way out in a time, you are capable of walking (depends on how much energy you have), shelter is nr one.
@@uncleartax Well, given the guy stays in hotels during his "survival" stunts I guess he's got those covered!
Tampons aren't good for bullet wounds, but they *are* great firestarters, especially if you can coat them in candle wax or a bit of cooking oil before lighting them. You can also use them as a stage 1 filter for purifying water (it will remove particulate matter, like sand and gravel, but NOT microbes or bacteria, so the water will still need to be boiled to make it safe to drink). If you fluff them up a bit, they can fit pretty snugly in the opening of a plastic water bottle.
Tampons have a place in survival kits, but their best uses aren't first aid.
the medics used the menstrual pads for wounds not tampons!! i knew 2 medics from the war and got it from them!!
Actually, tampons soaked in wax make a good emergency fire starter. But if I had a choice, I'd refer my propane torch.
Petroleum jelly is excellent for starting a fire. A little on some cotton can get a fire going in no time.
I've seen hand sanitizer used as well; it's basically alcohol in gel form.
fun fact when I was a child I saw these in my mothers bathroom and asked what they were. she said they were to stop bullet wounds.
No, I saw it in a cartoon once. When you’re in a falling house, wait until the last second, then step out the front door on to the ground as the house smashes behind you.
In 1974 I survived a 5 story industrial elevator freefall, I have never heard anyone even close to understanding what really happens, your suddenly weightless, you lose perception, no time to react
I did 🏦 security, ran freight elevators 🏢 around 3yr. 3-4x I had a freight drop 😟 3-5 floors, fall. NOT fun!

You're right that people don't get it. Gravity is really fast. I was working about 12 feet up on a scaffolding that collapsed. I reached up to hit a nail, next thing I know I was sitting on the ground. You don't have enough time to even think about jumping.
*you're, not your
WOW
As a Canadian I was definitely taught that eating snow will hasten hypothermia. I was also taught that if you are in an avalanche to blow on the snow so it melts a bit and you can then use the direction the water droplet travels to indicate which way is down (so moving in the opposite direction is up and therefore out of the snow). You can also do the opposite with bubbles if you get stuck under the ice. Though, as disorienting as being plunged under the ice would be, knowing which way is up is the least of your worries. The shock is almost as bad as the hypothermia and a lot of people die from involuntarily breathing in water.
Being Canadian is fun I swear. I love living in a country that hurts my face for 5 months. 😅
🇨🇦☃️
Sounds like a real hoot 😅
Come to Australia mate, Canada sounds like heaven. Nice easy temps to deal with, if it's cold put on more clothes or build a fire. hardly any nasty critters, and the ones you have are big enough to spot and avoid if you have a couple brain cells. Try avoiding our crazy critters in 48°c.
Don’t forget to keep your stick on the ice. 🇨🇦👍
@@shaneebz5292 Don't be fooled, Canada Geese are the frozen norths counterpart to Drop Bears. Lurking around every corner and just when you think they've left for the winter the fuckers come charging out of a bush.
There is a story of Polish-Canadian girl being stuck for three days in Tatra high mountains during winter due to the avalanche risk and snow storm… they found her healthy casually waiting for the rescue team thanks to her school training and extra equipment.
One thing to note. If you're stuck in the desert and you have water such as a jug or canteen, drink it. Don't save it for later. Your body needs that water inside you not inside a container. And you're actively dehydrating. It's not going to help you later if you're dead.
And plenty of people have died of dehydration with water in a container.
As an explanation for the last part, dehydration can seriously impair cognitive function, so people simply don't think about drinking their water if they're seriously dehydrated
Not quite the best idea... if you have a large amount of water and you are already hydrated and you drink all that water you will waste some of it on the ground.
A better way to phrase that would be drink it when you feel thirsty
It's called rationing
@@yasininn76 Rationing water in a desert usually hurts you rather than helping.
Another one i heard growing up: hiding under an overpass if a tornado hits is worse than just being in a field because of the wind tunnel effect. Best thing to do is get out of the car and lie down flat in a ditch.
Speaking from experience that’s all well and good until the tornado throws your car in the ditch at you.
@@Jude30as opposed to getting stabbed with a 2x4 going 150mph.
There’s no truly safe place in a tornado, but the safest place is anywhere that won’t have debris hitting you horizontally by making your horizontal presence as slim as possible. Be it in a ditch, a bathtub, a basement, the shore of a pond/river, or even just laying down on the ground.
Stand in the road and accept your fate like a man
@@Atlassian. it’s not really disputed.
When you break it down the winds are still hitting you and debris can do the same… couple that with the fact that winds can speed up under bridges and it’s just not a good idea to be under one.
@@Fetidaf If you can find some kind of drain around the overpass though, i would go in there.
My grandfather (born 1907) worked in a grocery store as a teenager. He was unpacking boxes of menstrual pads and asked his boss what they were for. His boss told him they were for polishing cars. So Grandpa took home a box and did just that. Obviously, tampons are for areas of the car that are harder to reach or need a little more scrubbing power.
My great-grandfather had to explain what pads were really for so grandpa wouldn’t use them on the car again.
this right here is why we need unisex sexual education
@@SlipNperiodSlideFuck no, I wanna see more people cleaning cars with tampons, that shit's hilarious
You can usually tell if a large colony of bats live in a cave because they often leave a deep layer of guano on the cave floor, which is definitely not a place I wanted to seek shelter in.
Lol
Considering the fumes from it are deadly, I agree.
But then you could make Gunpowder!
I don't know how. I just know Saltpeter is involved, and it's found in Bat Guano.
Yes, you are very likely going to smell them long before you see any visual signs.
guano is good for firestarting
I always thought that the idea to jump in a falling elevator (or crashing airplane) was intended as a joke
I mean, if you're in a plane crash, there's not really much you can do anyway, surely?
It's a child's logic: if you jump you hang still in the air
Physics says it would work but you'd have to jump at the exact same force at the correct time. The one problem is any ceiling above would hit you as hard as the floor would have. Science sucks lol
@@sd-ch2cq please explain.
You would have to be a stump to think this was a good idea.
Canadian here, 100% was taught IN SCHOOL like 25 years ago (early grade school) never to eat snow for hydration because of the exact same reasons listed here. Ill still take a bite once in a while just for joy though.
It is correct that ice can cool your core temperature it is beyond ludicrous to say it will dehydrate you. With the exception of perhaps the tampon advice this video has told people to do the wrong thing in every circumstance.
@@apathyguy8338did you even listen to any evidence given or just take the topics at face value?
I'm a New Englander and we were taught the same thing in elementary school
Depends on your acclimation, the temperature, melting method, and density of the snow IMHO. Melting compacted, heavy, wet, snow is easy with heat from your hands or another external heat source. For example the sunshine through your windshield. There are many scenarios in which using snow as a water source can save your life.
Ok then how did that guy who was trapped in his car survive on snow
Another famous myth is drinking from cacti in the desert. *Some* cacti are safe, but others contain oxalic acid (including some of the famous barrel cacti that are supposedly safe), and you can badly burn your mouth and esophagus trying to drink from them.

One recommendation for the falling elevator is actually bend your knees rather than lie down completely.
Firstly if the lift is falling from a height that gives you enough time to lie down then you are probably dead anyway.
Secondly, as long as your knees are loose, you will crumple achieve the lying down without the delay. Locked knees - the panic reaction - will break your legs, but loose knees will crumple. The sudden sitdown will hurt your backside, but that is, for most people, well padded and so you'll be alive.
Trust me on this one - I've personally done it. I know it is NOT impossible for a lift to fall down a lift shaft. The various things reduce the odds a lot, but it is not 0%. And I'm not talking a theme park ride either. However, I'd not recommend it - still hurts, just not as much as broken legs or dying.
"Snow is cold". Thanks Simon, those are the sort of facts I stick around for.
As someone who lives in Northern Norway, I can confirm this is 100 percent true
I was going to call bullshit since we've all seen pictures of snowy tropical beaches, but the guy holding me in his basement says that's actually just limestone or coral sand.

In a falling elevator, anyone who lights a fire to melt snow will live to regret it.
Especially if they fart.
I'm in a falling elevator right now, asking UA-cam for tips.
well, obviously you shouldn't light a fire in a falling elevator. It will use up all the oxygen inside and you will suffocate. 😇
It’s ok as long as you start the fire by lighting the tampon
But they _will live_
As someone who has been in these survival situations: its all down to luck, my example will be water.
I live in Canada and especially in the spring certain areas get the purest glacial meltwater. But that doesn't mean much if there's a dead moose a few hundred meter upstream.
It's one tip for high temps, like desert or just a brutal summer, do not conserve you're water. It is so easy to get dehydrated without realizing it cause your all like I'll just take a sip here and there. NO, if you are thirsty drink.
People have been found dead in the desert with water in their canteen.
In the end it loops back to luck. You either find water or don't, the water is good or it isn't.
Though I have heard of a good story about a guy found by search and rescue next to a river with dehydration so bad it damaged his kidneys.
When they asked him why he didn't just drink the river water he said "it might have given me parasites."
Sooo I mean it really is all situational.
Many years ago, a buddy and I were backpacking high in the Cascades in Oregon, along a crystal clear creek. We drank the water right out of the stream without boiling it. It was clear, cold and tasted absolutely wonderful. When we got home we had diarrhea for three days. We were so sick.
*your
What happened to the moose?
The story of the "dead moose" (for us Europeans more the "dead deer") in the stream I often heard from my parents when we drank from creeks, I always countered with: "And why should a dead dear lie exactly in that stream and that for a long period of time?" They most probably die anywhere else than that specific creek and get eaten within days, so I don't see any problem with that.
But cooking the water first won't be harmful anyways.
@@kamukameh what about all the fish that die in streams? Seems to me like all water everywhere must be spoiled
With that food thing- there's also plenty of things humans can only eat after processing properly, but animals can eat raw- like acorns. And, there are several things humans can eat that most other animals can't too- like onions/ garlic & most species of mint.

@@Frostfern94 lol I joke about that all the time because I'm also a night owl and HATE mornings (I worked 2nd shift for 4 years) 🤣🤣🤣
i’ve been on the street homeless in the winter and when we ran out of water i’d store some in bottles and use the heat that would accumulate in our tent (shocking it got extremely HOT in there) to melt it before drinking.
i’m so thankful that i had a decent grasp on common sense and enough of what i had previously considered “trivia” - it definitely saved me and the both of us many times.
I had an ex girlfriend whoos dad was an elevator repair man. His pay rate was very surprising when i found out. He had an unbelievable amount of knowledge in regard to his field..and for this and due to the importance of saftey and having good people in his position, he was very well compensated. He took his job very seriously. Trust that your elevator has been maintained by someone who had thier shit together, and is beyond safe. They make $100 an hour.. and they earn that because theres a lot to know to keep people safe, and they ensure that everything is in proper working order. He was a very smart guy (and a giant at 6-8). Knowing that people like him are responsible for elevator safety and how seriously they take thier job alleviates any worry i once had.
At that height he literally wouldn't be able to jump in most elevators!
@@paulhaynes8045 he wasn't just tall, he was massive. I'm surprised he could fit in one, lol. I heard a story that he got into a fight with another driver, who had a friend with him. He only had his daughter with him, but beat he both thier asses despite one of them hitting him in the head with a crowbar while standing on his hood ( probably couldn't reach him otherwise haha). I didn't catch how old she was at the time, but that's the story I got from her, and he confirmed it. Super chill guy.. if it happened like that he had no choice. No temper at all..
Yeah he probably wasn't making 100 an hour... unless he for some reason got a bunch of pay bumps that nobody else gets. Elevator repair says that they make less than 100k a year, so stop your BS.
@thomgizziz I repair elevators and my wage is $130 an hour. Which is just above standard rate these days so stop inserting yourself into people's comments with nothing to say except arguing. I pity your life. I hope you find something ro smile about even just on e rhis year.

"observe how other animals eat"
Now that you have found another animal, eat it.
thanks for the videos, this one has all good points
If you have
a. the skill to trap/kill it without expending more energy than you would gain from it, and
b. some equipment to cook it. Not fun to have food-borne diseases and/or parasites while having access to remedies, but it's so much worse when you do not.

Taking a rock to a lot of animals is a good way to get killed. Humans aren't particularly strong, nor particularly fast. Please don't actually try this. Many animals are extremely dangerous if in distress. Some deer for example can kick at 700PSI, and if you get hurt, whether minorly, or severely without any medical supplies, or medical knowledge on how to treat your wounds infection will become a massive risk. @@Carewolf

Actually, putting the fire at the entrance of the cave is extremely fangerous because the air from outside pushes the smoke back in. Cou terintuivel, you should build the fire at the back of the cave as the smoke will travel along the ceiling, and go out.
Cave shelter pro-tip: if seeking shelter in a cave or under an overhang during a lightning storm, DO NOT sit directly in the mouth of the cave; a lightning strike on the rock face could arc and jump across the space from the roof of the opening to the floor. You don't want to be sitting there.
well shie, then where do you sit if you also want to make a fire for warmth/food? Just cry?
The back of the cave is fine, just don’t sit directly at the opening if there’s a lightning storm going on
Actually the newest research suggests that lighting a fire in the back of the cage is more favorable than in the front because it creates a circular air motion drawing fresh air in.
this !!!
Yeah, I was going to write this! You are very true, they have found scorch marks at the very back of caves where ancient Humans dwelled.
@@lylemitchell1991 Also heat is traveling in cave longer this way so less heat is lost and cave is more bearable to be in.
See, this is why I have trouble listening to advice from the experts ..... cos for all I know they'll change there minds next week. LOL
If I ever find myself in a falling elevator, I'm going to stand on my head. To see how far I will be driven into the ground.
If there was ever a time to practice cock pushups, that's it. Not only can you say you literally drilled it into the ground, but you technically followed the correct safety advice too, as well as Tenacious D. It's a win-win-win.

I have a feeling your head would end up coming out of your arse, but it would be an interesting experiment I must admit 😆
As a former athletic trainer I can say that tampons can work to control nose bleeds. I wouldn’t use it for bullet wounds precisely because it just becomes soggy. In a nose the nostril would limit how much it expands but that’s about it.
Don’t use them for actual wounds.
Leaving the tampon in the wrapper and using it together with a bandage to provide additional pressure on the wound is the only way I can really see a tampon being useful in first aid, doing the same thing as a rolled-up bandage. Or, like, keep proper pressure bandages in your first aid kit.
My first aid instructors have always been very insistent that you never put anything in or take anything out of the patient. That will almost always make things worse. Your job is to buy the patient time for the paramedics to arrive, not cure them.
I always figured surviving a freefalling elevator would be similar to just free falling. While standing cage your head with your arms, make sure every joint in the legs, arms, and back are at least slightly bent so they don't lock out or bend the wrong way. Click your feet together so they more precisely impact at the same time, stand on the balls of your feet so the heels don't impact first, and lean forward and slightly off to one side. The lean is so that when you do impact you don't land backwards and increase the cances of a spinal injury or head injury as only your hands are back there to shield your head, and the leaning to the side prevents falling directly forward where the elbows will hit the ground and get pushed out of the way exposing your face to a high impact. Landing to the side instead presses the lean side arm into the head allowing it to act as a cushion. Your arm and jaw might break, but your chances of a fatal head injury are less
06:38 That one is only toxic when the ibotenic acid has not been decarboxylated, cooking will make it non-toxic.
You will however discover why we have depictions of flying reindeer.
Maybe part of why the guy survived since he still had a car available. Having the ability to go into shelter that can maintain some heat for a period of time (although the internal temperature will level out with ambient at night, that said a car can become a green house trapping heat if it is sunny) you may be able to heat the snow enough to melt it.
Not to mention, snow is an insulator so it'll help keep your body heat inside the car rather than letting it all escape. It's not a great insulator but there's a reason people survived in igloos for thousands of years.
Although tampons aren't good for a first aid kit, maxi pads are. I was in the Nordic Ski Patrol back in the late 70's and I was told to buy maxi pads to fill out my kit instead of standard gauze bandages. You could get a box of the former for the same price of one of the latter.
Back then they didn't have "wings" or any other things so they were basically just sterile gauze and worked quite well as a bandage.
And with regards to melting snow, you're better off keeping a small amount of water unfrozen put it in a pot and drop the snow in the pot. I did a bit of winter mountaineering back then as well, and I kept a bota with water under my clothes to keep if liquid. If you try to melt just snow in a pot, it takes a lot of fuel, assuming you have a camping stove, because as Simon noted, it's mostly air. Melting it in the water first, means you use a lot less fuel.
And keep your boots at the bottom of your sleeping bag when you go to bed. That way, they don't freeze.
Also diapers. Always rode my horse with a diaper in my trail bags.
That is terrible advice. Maxi pads are going to leave behind fibers whose removal from a wound is screaming torture. Buying them instead of proper gauze is planning to fail or sociopathy.
no, they were never sterile. so this was an odd thing to teach
Then again, my local red cross instructor taught us to "check for spine injury" by lifting a persons leg and hitting the sole of their foot/shoe to see if it hurt (Not joking, he taught us that as part of a first aid course..... I was too timid to say anything, but I hope that guy never actually "helps" somebody with an injured spine
Like quicksand, I was told falling elevators would be a much more common hazard.
And lava. I practiced avoiding lava when I was a kid.
One more thing to add to the elevator part. There are buffers in the pit for that reason (hydraulic, spring or polyurethane, depending on the nominal speed of the elevator, which is kinda tied to the travel height of it). Not sure if this was meant by the "crumple zones" as thats not really a thing at least on elevators i work on. Falling on buffers isn't going to be a pleasant thing, don't get me wrong, but its also not gonna be like dropping on solid concrete either. Air working as a buffer is also kinda debatable as in elevator shafts that can have problems with piston effect, they tend to add air relief holes to negate that. I guess technically you might have some air cushioning the fall but not really enough to make a difference.
A note on snow.
It takes more than twice a much energy to melt snow as it does to raise it to body temperature. Plus what it takes to raise the temperature of the snow to the melting point.
Let's say the snow is at 0 F (-18 C). Per gram it takes
- 9 cal to heat the ice to 0 C
- 80 cal to melt the ice
- 36 cal to heat the water to body temperature
Total: 125 cal
Vs: Just 36 cal to heat water from 0 C.
More of this kind of video, maybe a sequal about undderated effective survival tips, like using sos pads and the square batteries can be extremely effective at lighting even damp wood, or how covering your head with a hat hood etc is actually better than leaving it exposed in a hot desert environment despite it seeming like wearing nothing or as little as possible would be better for staying cool (i don't remember how this works )
This whole video was kind of dumb. Like how often do people find caves (rarely)? How often are people stranded or lost and there is a cave nearby (almost never)? How often do elevators freefall? (Never)
@rubiconnn well the frequency of caves depends on the terrain, and survival knowledge by nature is something you learn but hopefully never have to use, the elevator one I'll give you but it's probably a common misconception among older people, after all the myth was popular enough to appear early on on mythbusters. But it's still interesting, I wasn't previously aware of the crush zone or that lying flat was better, sure I'll likely never need to apply that knowledge but this is ultimately entertainment ans at least personally I was entertained.
@@rubiconnn But they were all fairly well-known survival tips, and all of them properly corrected.
I'm sorry you're so sheltered.
the covering up in hot environments works because the sun is a deadly lazer, and clothes are very effective at blocking UV light
not getting severe sunburns is better than "staying cool"

On the topic of eating snow: *never* do this. Even if you were to assume (as Simon did for the sake of his excellent explanation) that the snow is uncontaminated by animal droppings or man-made chemicals, well, the problem is that you would really have no way of knowing for sure. Even snow that looks pristine and perfectly white could be contaminated in some way. Unless this is extremely deep snow, it would be difficult to gather any appreciable amount without also inadvertently scraping up some of the soil and dirt under the snow as well... and we all know that soil is chock-full of various types of bacteria, most of whom aren't pathogenic, but some of which are, and in some cases, lethally pathogenic like clostridium botulinum.
In the absolute worst case scenario, if you have no choice, try to at least boil the water you get from melting snow before drinking it. This won't save you from chemical contaminants, but it may help protect you somewhat against the risk of contracting typhoid fever from bacteria in the snow. Ideally, though, if you must forage for drinking water far from civilisation, you would start doing so _before_ your current supply of water runs out entirely.
Of course, there's the problem (as Simon mentioned) that snow is mostly air, so trying to obtain drinking water from snow is a _very_ inefficient process which is further compounded by the fact you'll have to do this whilst trying to avoid freezing to death along the way. Hopefully you have a buddy or two to help divide the labour a bit.
So what's the best way to survive one of these extreme situations? Don't get into an extreme survival situation in the first place. Check the weather before you go out, and if you have any reason to doubt your safety, don't go. Above all, prepare accordingly whenever you venture out far beyond civilisation, and make sure that your friends and family know where you are going, so that if you don't return at the expected time, they'll be able to notify the authorities to send someone to find and rescue you if you get into trouble.
Stay safe out there!
Growing up in Wisconsin, every kid I know would always eat snow, all winter long. Nobody that I ever heard of got sick from eating it.
Idk man, I live in Ohio & we've been eating sno-cones we made ourselves for years. & idk what you consider extremely deep snow, but an easy 6 inches is common, and you won't get anywhere near the ground here. When you say extremely deep in thinking over 6-8 feet. That's not as common.
Honestly, last bit of advice might be the worst advice. Everyone has their own lives.
Its like being afraid of skydiving bevause there's always a chance your main amd back up chutes fail. Or never climbing everest bevause you're afraid to die.
The point of learning to survive extreme situations is so that you can take part in activities, amd be ready for the worst possibilities.Humanity would never have come to where we are today if everyone followed your advice
@@hteetyit’s more like not climbing Everest because there will be a blizzard or a storm or something. He ain’t saying never do any extreme sports but make sure that it probably won’t be in dangerous conditions and letting people know where you’re going isn’t exactly a bad idea in case something does happen. It isn’t bad advice to attempt to make dangerous activities less dangerous.
It doesn't have to be super deep. As long as the snow is undisturbed (e.g. not compacted as a result of something walking over it, and with no visible discoloration) and you can scoop it without scooping up dirt (which is usually pretty easy in snowy areas) you can readily collect pristine snow, which is effectively rainwater (which in turn is basically distilled water mixed with ambient air). As long as the snow is outwardly pristine, contamination only becomes an issue if the air is contaminated, in which case you're breathing in contaminants anyway.
As a first responder, the breakdown of stopping life-threatening bleeds is extremely thorough and well-explained. And I loved the emphasis on identifying what will kill someone faster, bleeding or infection from unsterile packing material. People overestimate how much blood is in the human body. An average sized human being can bleed out from a severe bleed within minutes, and even if the bleeding is stopped, it’s likely the person has already gone into shock, which in its own right is maybe one of the biggest medical concepts that is misunderstood and needs its own debunking video.
First priority in a survival situation if you are able to breathe and are not bleeding profusely is to maintain your core body temperature. That means finding a way to stay warm in cold environments and cool in hot environments. Hypothermia or Hyperthermia will end you within minutes to hours in extreme conditions unless you can insulate yourself from them somehow. Get out of the wind and into the sun if possible in cold environments, then find a way to insulate yourself from the ground. Leaves and branches work well if you find yourself below tree line. Make a mat with them first. Do not exert yourself to the point you sweat. If you must exert yourself heavily, remove clothing so it doesnt get wet, and don it again as soon as the task is complete. Build a fire if possible. Dry out any wet clothing. Make a lean-too or dig a snow cave if possible. Find a hollow tree or a V between some rocks. Squat on your feet and huddle for warmth if you cant insulate your butt from the ground. Minimize contact with cold things.
Desert survival is similar. Avoid hot things like direct sunlight and the ground or rocks that have been heated by it. Find or make shade, and only exert yourself between dusk and dawn.
In either case, stay put unless you know exactly where you are, and how to to navigate back to civilization, and have the strength and equipment and supplies necessary to do so. Carry an EPIRB or a phone with satellite distress calling capabilities like the Iphone 14 and later models.
Most of all, don not enter the wilderness unless you are prepared to spend at least a couple of days sleeping rough, and can summon help if you get hurt or lost. Carry a map and compass and know how to use them.
As an ultimate Fail Safe, elevator shafts have rails that taper inward for one-story+ (min 15 ft). as they descend below the first floor.
OTIS is 1 of the main, big US elevator companies.
Yup. The Otis Safety elevator. It's what made high-rise buildings practical. Otis famously demonstrated his invention at The 1853 Wold's Fair. It's still one of the most successful publicity stunts in history. From Wikipedia:
"At the New York Crystal Palace, Otis amazed a crowd when he ordered the only rope holding the platform on which he was standing to be cut.[2] The rope was severed by an axeman, and the platform fell only a few inches before coming to a halt.[5] The safety locking mechanism had worked, and people gained greater willingness to ride in traction elevators; these elevators quickly became the type in most common usage and helped make present-day skyscrapers possible."
Talk about confidence in your own invention!@@DavidLLambertmobile
@@DavidLLambertmobile Otis was also the the man that invented the first practical elevator emergency brake. I would love to be able to go back in time and watch his demonstration of the invention before that crowd. Chopping away at the cable holding him up, only to drop a few inches as the brake kicked in automatically.
@@DavidLLambertmobile Size is comparable to Finnish Kone and neither is the worlds largest elevator manufacturer.
3:12. First concern is shelter. Hypothermia can kill in hours. Then water. You can survive 3 days without water. Food is actually relatively minimal concern. You can last about 3 months without food. Itll suck, but you'll live.
Hell, the average American will make it about a year, provided they could get salt and a few vitamins.
@@kerim.peardon5551 straight facts
Hours if you're lucky. If you're wet, especially in water, it can be a matter of a few minutes. And often times it's not the hypothermia, it's the stupid stuff you do because you're brain is too cold to operate properly. The survival without water can vary. My grandfather lasted roughly 2 weeks, but he was inside with properly maintained room temperature and was going to die regardless. I personally managed nearly a month on basically no food. IIIRC, it was like a cup of yogurt a day due to a bad stomach infection. I felt fine through out, so I'm wagering that something closer to 3 months would be possible, although it would come with numerous longterm health impacts.
This is why it's generally body temperature before water. (And it absolutely has to be clean, diarrhea can be absolutely fatal if you're already low on drinking water) And water before food.
Shelter is only the first concern in extreme conditions. Typically, you'd want water first.
@@satgurs incorrect. You can still freeze to death when it's 50 Fahrenheit. Unless it's 98.6 degrees outside you're losing body heat to the environment. Shelter is always first. Thanks for playing though. Better luck next time.
I think the mistake of using tampons for bullet wounds is also in part people forgetting that certain words in one language don't mean the same in another. Tampon is a french word for buffer and if the label of a medical gauze package includes French it will also include the word tampon. Likely American soldiers heard and say the word a lot around the French in WW1 then when they got back to the USA and heard the word used to describe feminine hygiene products they where like "did you know those are used for wounds in battle?"
Thank you so much for bringing up these myths. One I didn’t know personally is the eating snow one. One I’ve been trying to dispel is the tampon one. I’m an avid shooter and trained in field trauma, and this is so pervasive.
Astonishingly persistent, too. I've been shouted down for disagreeing with it, despite mine and my instructors credentials being *significantly* better (and including actual evidence) than some dumb mook who barely passed medic school and never saw an actual GSW in his entire three years of service pushing the myth.
Yeah, there was a video a while back of Russian conscripts being told by an instructor to ask their girlfriends to send them tampons for improvised medical kits for the purpose of plugging bullet wounds if they couldn't get a real one....
Most elevators nowadays aren't even cable lifts, They're hydraulic columns.(think an old car antenna) Even if there was a failure and the elevator started to "fall", the hydraulic column would fall so slowly that nothing would happen. They've been phasing out cable lifts for quite a few years now I think.
Hydraulic elevators have a maximum height though. They haven’t been phasing out cable(traction) lifts at all. In fact they are still the go to for high rise applications. They’ve been moving away from steel cables in some applications, using high strength rubber belts with steel reinforcement within them. But if you have a high rise thats 500ft tall, you’d need to dig a 500ft hole in the ground for your piston. Not to mention the massive tank you’d need to hold all of the oil. Plus hydraulic elevators are just too slow. Going from floor 1 to floor 60 would take you several minutes. Cable suspended traction cars are capable of going upwards of 1600 ft/min and beyond. Until we master the art of levitation, traction elevators will always be prominent in buildings taller than 50-60 feet.

I remember learning in medic training to pack a wound with gauze then wrapping it, and taking a timed test to do that under a certain amount of time. honestly, one of the most fun tests in medic training.
And to use gauze because it wouldn't leave tiny fibers behind.
In around 1981 I was on a school field trip to Grand Coulee Dam. We were in the dam in an elevator going up. This was back when you could still go inside the dam on tours.
The elevator stopped and dropped maybe about 10 feet, then went up again, then stopped and dropped 10 feet or so again, then started going up and then stopped and the door wouldn't open. We were stuck in that elevator for 45 minutes or so. One kid was saying he would just jump right before the elevator hit the bottom. The rest of us told him it doesn't work that way. The elevator was stuck at the top of the dam, so it would have been a long fall. Later on a fireman told me about the safety backups in an elevator and that were were safer than it seemed. But I think about that day every time I'm in an elevator.
I only rode Tower of Terror at Disney'sHollywood Studios once. That was enough I hated it. Sounds like a worse version of your tale.
If you have an environment where you can keep warm, such as the buried car of the man who was trapped for two months, you can put the snow into a vessel to naturally melt. Once you have enough, that would be safe. However, remember opening your "igloo" to get the snow will lose you some of the built up heat and the snow itself will cool the environment as it melts. Life is a balance. 🙂
Elevator horror stories are pretty rare nowadays, for the reasons you cite, but if you want to be freaked out read old newspapers from a hundred years or so ago about early elevator technology and it's like mass carnage. Scary stuff.
The incident in the Empire state building, where a lift fell dozens of stories comes to mind. It was completely and utterly obliterated, including its human occupants... But that was like a century or so ago, as you mentioned there were no failsafes yet back then.

I was told surgeons hate dealing with quick clot. It is certainly better than not using it when your buddy has a gaping bloody hole, though.
Was told the same thing, was also briefed on the whole tampons for a bullet hole from a Corpman that served in Iraq, so far he is fifty fifty.
better to piss off a quack than bleed out!!!
@@JaredLS10 And I was briefed by former SF medics during my training that tampons are a bad idea for exactly the reasons he listed. Experimental evidence also supports their use for GSW being a horrendous idea.
Your Corpsman friend was, like many medics who confuse six months of training for being on par with medical school and research experience, wrong.
Quick clot is a last ditch effort if pressure doesn't work though. Have used it a few times on patients in the field. Understandable why they don't like it.
4:10 I saw a video saying it’s actually worse to build the campfire at the entrance. Best to have it in the end as it will create a less toxic air flow. Still a terrible idea without a hole in the roof however
Yeah I saw that one too. Simon here actually giving people some accidental dangerous tips, oops!
Yeah was about to comment the same, putting it in the middle or the back makes hot air/smoke to rise while cold air comes in from the entrance. Blocking off the entrance would just pump smoke into the cave, especially if the fire is too big or the entrance small.
I saw it to only yesterday, 25 myths you believe are true.
There are a lot of considerations for whether to even use a cave as a shelter. The slope of the floor and ceiling, the direction the cave-mouth opens toward, the caves general shape and depth, and whether the cave is used by bats. If the cave is used by bats, waking them up isn't the worst thing. The worst thing is that they poop on the floor of the cave, and that poop attracts a ridiculous number of insects.
Now, we'll assume the cave isn't used by bats at all. The important considerations are what direction does the mouth face, the depth of the cave, and the slope of the floor.
The direction the cave faces will impact winds around the cave, which will determine how air circulates in the cave. Along with the cave's shape and dimensions, and the local geography and flora. Air flow relies on smooth surfaces, and in caves, surfaces are generally anything but smooth. These differences cause eddying in the flow, which serves as a barrier. That barrier will trap gasses produced by the fire, such as CO and CO2, and suffocate you in your sleep. Especially if the floor where you are is lower than the entrance of the cave.
If you are using a cave as a shelter, putting the fire at the entrance allows the wind to pull the smoke across it and away from the people. You want to sleep near your fire for warmth. You need to know how to place a fire.
Use no more than the first two or three meters of a cave, build a fire-pit, use rocks as heat-sinks and reflectors, and keep your fire small. Any fire meant for survival should always be small, just enough to keep you warm, and maybe heat some water or cook something. You aren't heating the entire cave. And you don't want to spend hours looking for fuel for your fire.
Simon's videos should be regarded as entertainment, not reliable information. He tends to put out stuff that is not well edited. His mistakes are sometimes left in the videos.
There should be a disclaimer for the don’t eat snow… You shouldn’t eat snow if you’re stationary and trying to stay warm, then you should be drinking water, preferably boiled and still relatively hot…. That’s a super important distinction.
But if you’re active and staying warm through movement and work, eat as much snow as you’d like, BECAUSE it’ll cool your body down and the goal is to avoid sweating at all cost when you’re working or being active out in the cold.
I thought the elevators that were hoisted by a cable (the other type has a hydraulic post that is below the enclosure) lifted the thing by a leaf spring. If the cable is separated or sheared, and there's no tension pulling up on the spring, it relaxes and the ends protrude (extend) past the car and catch in the rails.
Therefore, the elevator cannot freefall.
You stay there and wait for the car to be lowered, or they get you out through the door in the top/ceiling of the car.
7:07 they are often included in survival kits as they contain a lot of cotton wool in a small package and so are good for starting fires.
But mostly, because there's an astonishingly persistent myth that they're useful for gunshot wounds, and that appeals to the type of idiots who buy survival kits.
I remember when in Boy Scouts, some younger scouts from a different patrol group grabbed rocks from the river to make a fire ring. No one realized their stupidity until a rock fractured and sent shards flying. Luckily, no one got hurt, but damn! The Scout Master was pissed!!!
*Regarding eating snow:*
Surely, there's a break-even point... There's a considerable difference between the energy required to melt solid water near 0°C and -273°C.
I can't remember the term for it, but there is an extremely large (relatively) amount of energy required for a substance to actually change states, so the last little bit before actually turning into liquid would take alot more energy to warm up than any of the other "degrees" it had already warmed, likely more than all of them put together. Not to mention your body may not need to warm the water anymore once it is liquid, but it will still be losing heat to that water until it reaches your body temperature.
Cause I'm a nerd, tried to find the actual amount of energy needed for phase transition and found this:
"Using the equation for a change in temperature and the value for water (334 kJ/kg), we find that Q=mLf=(1.0kg)(334kJ/kg)=334kJ is the energy to melt a kilogram of ice. This is a lot of energy as it represents the same amount of energy needed to raise the temperature of 1 kg of liquid water from 0ºC to 79.8ºC"
That said it's not instantaneous, and the same energy spread over time has different impacts, and there's a whole bunch kf complicating factors (snow n someone's stomach and a block of ice in a lab aren't exactly identical), but the gist is the same, it's going to draw a lot of heat from your body and if you're in an environment where snow is the only water source you probably need to keep as warm as possible.

@@XDeserak thank you. This is what I wanted to do, but I'm a lazy nerd lol
@@an0mndrI think the term is latent heat capacity
@@ruledtrendy5066That's right. The energy required to change a substance's state is called latent heat, and energy that changes a substance's temperature is called sensible heat.
I don’t know if my son watched this video, but we were in an elevator (which he hates anyway) and as we were stepping out of it he told me that if it fell we shouldn’t jump. 😂

it will cool you down but that is no problem when moving and many times beneficial to stop you from sweating.

there has been stupendous amounts of videos saying "ACTUALLY you should never eat snow" and that it´s a myth you can eat snow if you´re thirsty.
it´s just the reverse of the reverse. the "gotchas" went 360.
of course if you´re hypothermic or even just cold in general it´s not good to eat snow and you should melt (or even boil) the snow when possible. that way you get way more water in you if you´re thirsty.
but if i´m dying of thirst i´d still eat snow no matter how cold i was if i have no access to melting the snow other ways.
only in this situation "it depends"
but the "fact" that you should NEVER EVER eat snow is a billion percent FALSE.
i always try to respond to vids with this false "fact" to try to educate people.
i bet simons writer has never been in a forest or seen snow.
Food tip. Rub the juice or the thing on your skin. A patch test to check for allergies keeps it there for two days. If you know you gonna be stuck for a longer time, start early and start with rubbing it on, if you have no responce, keep it there for an hour, if the next day you still have no responce take it a step further.
Also not fullproof but it is a bit safer then ingesting immediately.
Drinking pee in a desert, or at all.
Pee is very salty and actually dehydrates you quicker.
Salt pills are taken so to help hold water and add electrolytes. Football players do it in summer camps all the time.
Absolutely. Also, there's plenty of water in the desert if you know when and where to look. The WHEN is the most important part of any choice you make in an arid environment.
And you can only drink it for about a day at the most. Even then you're risking kidney failure as your body is trying to get rid of it.
@@Mercurio-Morat-Goes-Bughunting exactly. Sometimes a piece of plastic comes in handy to get it as well. If you dont carry a small plastic bag to collect trash on your walks, it's a good safety net in an emergency for water.

The trick is to stay in the shade during the day and get things done at night.
You really shouldn't have to pack a wound (Chapter 4) unless it's in the crotch area or armpits.
The best thing you could learn to do is how to apply a tourniquet or fashion one from a shirt, belt or bandana and a stick.
In the case of gut wounds use a clean dry pressure dressing and do not try to stuff intestines back inside a abdominal cavity.
Chest wounds you would like to have a seal dressing (can make one with a ziploc bag and tape) while monitoring for pneumothorax.

For years I've argued that lying flat in a falling elevator was your best bet, glad to hear the experts (there are experts in elevator fall physics?!) back me up.
Distributing the weight more lessens the impact areas force.
Nah, this is nonsense
The elevator advice seems bad. 1) there is 0% chance that you are going to be able to lie on the floor of a falling elevator. You don't have time to react and you're going to be floating off the floor, probably up against the ceiling for most of the journey 2) You don't want your legs to act like a crumple zone? Just take the impact directly to your vital organs and head? 🤔
@@CleverAccountName303 If you're able to stand at all, standing with knees and hips lightly bent seems the best choice. They are our bodies' built in shock absorbers, even if they won't be able to do enough to save us in this scenario.
The whole snow thing isn't without precedence. I read a book about the Antarctic explorer Sir Ernest Shackleton. He said when they were holed up in their tents in minus 50 degree temperatures, what they did was to pack snow as tightly as they could into their drinking flasks/canteens. Then they would put them in the bottom of their sleeping bags, the radiant heat from their bodies was enough to melt the snow but not enough for them to suffer hypothermia. This was just enough for them to keep going. 'Endurance' if your interested, a very good read.
I just watched a similar video a few days ago that said not to build the fire next to the cave entrance, because the wind/airflow will push the smoke into the cave. They said cavemen always built their fires in the back or middle of the cave, so that the air would come in and wrap around taking the smoke out with it. I'm no expert though, so idk which video is correct.
Ive survived an elevator fall. The air bag thing is real and i felt it. Happened so fast i barely had time to think. I was a kid playing around with an elevator having a game with friends racing each other to the bottom and after like the 4th time it happened and i just remember feeling butterflies in my tummy and then a feeling like standing on an inflatable matress after you let the air out. The doors opened and the floor was a good few feet misaligned with the ground floor. I had to jump down. And i looked up at my friend who was coming down the stairs (we where racing) and he has like "How did you get so fast?". I hate elevators to this day.
Another elevator survival tip: Do not attempt to leave an elevator that is stuck/malfunctioning/misaligned; call for help and/or use the emergency phone inside the elevator to call for help and wait until firefighters or some other personnel arrive and only exit when they say it's safe.
If you're inside an elevator that's stuck and it suddenly drops again, you're probably going to be okay because of all the other safety systems. But if you're attempting to climb out and it sudden drops, you get cut in half.
You might feel silly just standing there waiting for possibly hours when the door is open and you could easily climb out, but it's not worth the risk.
@sykes1024 Yeah. Wish someone told me that as a kid. I do remember my parents mentioning something like that after the fact, though, and then everyone saying, l was so lucky i didn't get cut in half. You know how it goes with all the neighbors talking about something big that just happened 😅.
It wasn't an air bag. It was some sort of an emergency brake that stopped the elevator.
Elevator shafts are not airtight, so such a pocket would not stopped elevator completely, just slightly slowed down the final impact, it would not be a few feet high (air compresses quite effectively) and finally once the door was open, even if the shaft has been airtight (which it isn't), the "air bag" would leave through the door and the elevator would have fallen to the ground.
If you jump in a lift that isn’t falling, it triggers the lifts emergency brake. Trapping you in the lift.
Use this knowledge with care.

The problem with elevators, is they typically fall UP, not down. The counter-weight is heavier than the car and contents. To fall down, an elevator would need to lose both braking and cables. To fall up, you just need to lose brakes.
I knew all of these already except for the tampon one. I'm surprised to think that people have thought of using them for such a thing. Great video with good information, wish it was longer with more scenarios.
2 months trapped in a snow-covered car…
The stench inside the vehicle must have been absolutely insane.
One morning, my car was absolutely *buried* under the snow...I got enough off to open the driver side door (yes, I DID clear it properly before driving off!) and dang - it was *warm* in there! Proof that igloos are a good idea.
Regards to the elevator I don't think everybody knows that fact that they are traveling at the same exact speed that the elevator is dropping. So the elevator and the human are traveling at the same rate accelerating at the same time prior to that. Ergo lay flat just like gravitron carnival rides
The elevator falls first. So you are not going to be touching the ground in a free fall situation. Even if you are only one centimeter off the floor, you have no control to maneuver yourself. The elevator will start to slow down very slightly from the air pressure buildup, which gives you about 1/10000 of a second to collect yourself and get in the "right" position. Good luck

The "stabbing a stick into the ground to mark the shadow's movement to find North" is because you actually can't immediately tell which way is North based on the sun alone.
- For most people, the sun will have a prominent Northern or Southern "lean" in relation to how far away you are from the equator. This lean can become very extreme as you enter Winter or Summer.
- With that in mind, for most of the day you will only be able to discern that the sun is up. If you naively think "it's before noon, so the sun should be in the East" or "It's afternoon, then the sun should be in the West" then you _will_ very quickly make yourself _more_ lost as what you thought was East was actually South/South-East _(which is one of the many reasons why you are more likely to survive if lost if you simply stay where you are)._
- Even when the sun is rising or setting, that still won't get you due-East or due-West but South-East or South-West _(if you live in the Northern Hemisphere)._
However, when you mark how much the shadow moves over time, you aren't tracking the sun's location but the sun's _movement._ That is how you can get a much more accurate understanding of East/West by using shadows instead of the sun directly.
If it's night time, look for the Big Dipper. The last star in its handle is Polaris - the "Northern Star," named such because no matter what time of the year you're in, that star will *_always_* point you North - assuming you're on the Northern Hemisphere. For those in the Southern Hemisphere there's "Sigma Octanis" that always points you South, but apparently it's pretty dim and somewhat hard to spot by the naked eye?
As for discerning if food is venomous, simply have it bite/sting you and see if you react. _(sorry, had to reference the venon v. poison meme, lol)_
To discern if it's poisonous, there's actually a surprisingly long series of checks that can take a few days to fully rule out if a food is poisonous.
The steps start with "crush between your fingers; if they start tingling after a few minutes, it's very likely poisonous" before putting some of the juice on your lips, then your tongue until you eventually eat *_the smallest portion possible._* Then you just slowly work your way up to an actually useful amount of food. It takes a few days because there's a waiting period between each step, with the later steps having a waiting period of 1-2 days _each._
Of course, you would need to source a clean water supply first because a very *_very_* common symptom of poison in one's food (especially when it's at such small amounts) is food poisoning. . . . . .hence the bloody name "food poisoning," lol.
And once that happens, you can survive assuming you don't end up dehydrating yourself from your body's. . ."reactions."
With the tampons one:
There is such a thing as "pack the wound," which is where I think the myth originated from. The issue is that there's some prereqs to if a wound should be packed that I'm not qualified enough to state with absolute certainty. Ultimately your goal in such a situation is to stop the bleeding - even if it means losing the limb. You can survive from losing too much of a limb from having a tourniquet too high up, but you can't survive from losing too much blood.
I also want to take this opputunity to state:
DO NOT REMOVE THE GAUZE/TOWEL/WHATEVER IF IT'S "FILLED."
Yes, dressings need to be changed to prevent infection, but at that moment an infection is the _least_ of your worries. The whole reason why gauze is shaped that way with the notably large holes is so that the blood can have an area to adhere to through surface tension before clotting instead of simply running down the body clearing the way for more blood. When you remove the gauze, you're essentially ripping off whatever clotting has formed, putting the victim right back onto Square One.
Instead, you simply keep piling it on until the bleeding has stopped.
In fact, in serious wounds it's common to tourniquet the limb - if possible - while also piling on the dressings. Ultimately what keeps blood from large wounds from clotting is your own blood pressure. Stop the blood pressure and the blood is much less likely to simply push any micro-clots out of the way. Only after the bleeding stops do you slowly loosen the tourniquet.
Also, a limb can survive a surprising amount of time without oxygen. The concept that the body needs a constant supply is yet another half-truth. It's the _brain_ that needs a near constant supply. However, a limb can go without blood supply for close to 6 hours. If you've ever woken up with zero control over one of your arms for a good few minutes, that's exactly what happened.
Don’t put quick clot in a gunshot wound if you can avoid it, it has to be cut out once it sits. Use gauze to stuff the wound.
The shadow line technique for finding north is commonly useful when calibrating a compass. If you want your compass to point true north (and account for magnetic drift) then the shortest shadow of the day, cast by a vertical object, points north along a horizontal surface in the northern hemisphere and south in the southern hemisphere. I've used this on more than one occasion and it's also solidly reliable for determining midday, local time (as opposed to the time of the local timezone) if you're using sunsights for navigation.
In the absence of functional safety systems, jumping in a falling elevator has zero effect on outcome. Even at the moment of impact, you assume the elevator's speed - the speed imparted by the jump, then, by the time you hit the deck, gravity has undone the speed change you gained from your jump and you hit the stationary floor of the elevator at the same speed as the elevator was travelling at on impact - which is exactly the same as if you'd just stood there.
Caves are not the healthiest place to seek shelter. Never light a fire inside a cave. You'll burn up the oxygen - assuming that something flammable hasn't been gathering there for the past 20000 years and, well, that's one way to go out with a bang! Cave-ins are a feature of mudstone caves, generally not sandstone. If you hear a hiss or see a ghost, leave. A hiss indicates a sediment trickle which, in turn, indicates something's broken and you may not want to be around when the chickens come home to roost. Ghosts, and other locality-specific visual hallucinations, are a visual response to infrasound and infrasound, in any structure (including buildings as well as caves), is indicative of gradual structural collapse and typical of metastable structures which might hold together for years then collapse without warning. In short, if you're not a geologist, don't go deep enough into a cave to need a torch, lamp, or flame.
Dehydration by snow consumption makes no sense. Snow cools you down. You don't sweat unless you reach a certain internal temperature no matter how much energy you burn. So, unless snow can elevate your body temperature it can't kill you by dehydration. Hypothermia? Yes. Definitely. Dehydration? Not in this species! Otherwise, eating icy-poles would not be a thing in the summer because it wouldn't feel refreshing or drop your core temperature - which is something that can be a problem in the cold. So, your biggest problem in a cold environment is lack of heat and if it's that cold and you can't find warmth, it won't matter either way.
It cracks me up that you don't believe in snow dehydrating you. Facepalm.
@@randomname4726 I take my vow of abstinence from faith very seriously. Why should I believe in anything when belief is the basis of all deception and error?
That said, can you explain how a drop in core body temperature results in dehydration given that loss of fluid due to sweating is core temperature dependent, not a function of power...?
Here's a fun experiment - and I've done this a lot just as par for the course so I already know how it ends. Work up a sweat in the summer. Don't do anything extreme. You don't want to get to the point where you stop sweating or it will stuff up your experiment. Now, go indoors, take your temperature, and dry off. As soon as you've stopped sweating, take your temperature, again, then eat four icy-poles or, alternatively, drop some ice-cubes in the blender and scoff down the icy mix. Do you start sweating again? When you subsequently take your temperature, has your body temperature gone up or down?
I'll take reproducible experimental evidence over a piece of paper any day...no matter how official.
Trees can give shelter, but *light no fire* close to one - without checking for snow load on branches above. Collapsing half-slushy, warmed snow will snuff a fire, wet the burnables, AND cool you off.
Oh man, if you don't have more of these videos, please make more!!! This was so interesting especially about the snow, had no idea that would be so detrimental. You might just save lives with this video lol
I love when Dr. Venture posts a new video
The amount of lost goods inside of collapsed caves from fires is probably crazy
As a lift engineer myself they are very safe the brake can only lift if there is power to it, in a power cut the brake wont be able to pull the relay in that tells the control panel to lift the brake in the first place so dont fear, and 1 of those steel cables is strong enough to hold the lift on its own plus the device under or on top of the lift that is also a brake will pull in if the lift travels fast then the speed it is set to.
Lifts are safer than driving a car
In critical emergencies involving gunshot wounds, the pressure really is the critical element. The pressure against the wound is what triggers the body's natural clotting response. There's a lot of complex mechanisms involved, but the punchline is this: if you can maintain constant pressure for long enough the wound will close itself up, albeit in a weak manner initially and is extremely vulnerable to reopening. But if you are in an extreme situation and you have to move the wounded person in question, it's much more survivable if you're able to maintain pressure on the wound. The longer you can maintain pressure, the better.
You can use your body to melt snow and drink it, just depends on the situation. I did it on a survival course I took in the winter. With all the heat I was generating over the two days from all the wood I was cutting down and lugging around on my own to build my shelter, and then later smoke signal, and also to supply for a fire, I was burning a lot of calories and generating a ton of heat. So much so that I eventually had to remove my toque and walk around with my jacket open. Temps weren't super cold though, about -5 to 0 degrees celsius. It would probably be a different story in -30 or -40 temps as I know some folks had to deal with.
Point is, in my situation, packing snow in to my water canteen then putting it under my shirt to melt it wasn't exposing me to hypothermia as I was already boiling up from the 2 days straight of tree cutting and moving them. Of course, a fire to melt the snow and ice is always best, but you can use your body heat IF you aren't at risk from hypothermia by doing so. You just gotta be the guy doing all the work to work up all that extra heat. ;)
That all said I did break the rule and eat a bit of clean snow, but that was more for relief from all the heat I was working up. I melted as much of it as possible to drink later.
I'm struggling with a few of the conclusions:
First the advice to better not eat anything other animals eat and just stick to drinking water. I know from personal experience that indeed you can survive on water only but it has a significant impact on your energy and wellbeing. Considering that you're lost in the wilderness this is far from ideal and can create a life threatening situation. I have also observed monkeys eating certain legumes and followed suit which turned out to be fine. In a survival situation this could potentially save your life. I'd argue it would be worth trying a small amount first and determine how your body responds. Being able to find something to eat seems crucial to me for survival.
Second is the advice to not eat snow for hydration. Although I understand the risks involved, it seems clear to me that the example given of the man who survived two months while eating snow proofs that it can be a life saver. Without water a human cannot survive much longer than a week, so him surviving two months on snow proofs that he got hydrated while overcoming the downsides. Because of this I doubt the conclusion that the energy expenditure caused severe dehydration. I suspect that taking small amounts at a time would allow your body to recover without serious complications. it seems a risk worth taking over not surviving from dehydration.
The people who say you can survive x amount of days without food often seem to forget that this only applies if you aren't moving. If you are moving, because, for example, you're lost in the wilderness and are trying to find your way out of the wilderness, well then you won't survive much more than a week without food, and you'll be forced to slow down considerably after two or three days at most.
@@legrandliseurtri7495 Well, you'd be better of staying still than blundering around the wilderness in random directions, because that's more predictable for search parties.
He didn't actually spend 2 months stuck in his car. He was discovered on February 17th 2012. On the 28th of December, he drove a few metres. He also celebrated New Year's Day with energy drinks and vodka. And in mid January he attempted to walk to the nearest supermarket but gave up after falling 3 times in 10 metres.
And he did melt the snow before drinking it.
Regarding being lost in the woods, learn about the local flora and fauna, before you go anywhere, dress for the weather and carry the things you really need, including the means to protect and help yourself.
Back in the 90s, my mom's cousin was in an elevator that malfunctioned horribly... it repeatedly went to the 3rd floor and then went slamming to the bottom, then back up to the 3rd floor before crashing down again. This happened multiple times before he was rescued. He survived (although with pretty significant injuries) and uhhhhhh got quite a bit of settlement money out of that incident.
On the last one:
That only applies if you're staying in one place and not doing anything.
If you're walking and active, you generate body heat quickly.
You can easily wind up sweating.
Cold is ome thing.
Wet and cold is dangerous. Sweating is bad. Movies & video games where people get their feet wet in the cold...
Yeah, in real life, you don't get your feet wet in the cold unless it's necessary.
Anyway, the point is that in reality, thermal management may make eating snow necessary. To keep your body heat down to minimize sweating.
How much energy does it actually take anyway?
I've always wanted to the math and check if these ideas are valid.
I've been told not to drink very cold water when working in the heat because it takes too much energy to for the body to warm it up.
I've been told similar myths about it taking too much energy to digest food.
What I do know is legit it that you can't survive long without water.
Apparently, you have at most 2 days, maybe 3 if you're very lucky. Then cramps and stuff. You're alive, but not functional enough to get the water you need.
Without actual hard evidence I have a hard time buying into this idea that it takes too much energy to equalize temperatures.
If anything, the hazard is hypothermia if you're not active.
If you're active, "cotton kills." Because it absorbs water and holds it. When you stop and cool-down, you're in dangerger without a fire or warm-up.
Survival tip: get an audio book with advice from your grandmother. Play it constantly and follow the instructions... yes including such things as "Don't trust men with moustaches"
The fact that the elevator jump was ever proposed makes me feel good about my understanding of physics.
Idk where I learned this (probably on tv) but if you have 2 plastic bags (water tight) and you need to drink snow, you can pee in one of the bags and use the other to collect snow. The warmth from the pee will melt the snow and you can drink.
Heating snow with your body heat does not use more water than you get from it.
But it would drain a lot of energy.
I wonder about the fire in the cave thing. If you are seeking shelter from rain and/or wind you'd have a harder time keeping the fire going if it's near the entrance of the cave. Also, if the fire is in the entrance of the cave and you are behind it (deeper in the cave), any fresh air coming from outside would have to pass over the fire before reaching you, possibly being contaminated by smoke and carbon monoxide in the process. With that in mind, maybe it would be best to make the fire a few meters from the cave entrance and for you to stay between the fire and the cave entrance, so that you'd be closer to the fresh air coming from outside.
But then, I don't know what would happen to the toxic gases generated by the fire. My thinking is that since they are heated up by the fire, they would rise, so even if they have to leave the cave through that same entrance they would be closer to the ceiling, while cold air coming from outside would be closer to the floor. That's all pure speculation on my part, and I'm definitely not a specialist in the area.
I heard that for the fire in a cave it’s actually the opposite because heat in the entrance would make the part of the smoke that gets inside to accumulate instead of escaping. It’s an interesting point about the heat expansion of the rocks though. Seems like it’s a gamble either way.
Re tampons: they're great for starting fires. Set up your sticks/wood for the fire with kindling, light the tampon, and stick it under the firewood
Also not a bad idea to fill an elevator with tampons, just in case.
Great video, definitely love to see more on the subject
