Wish I could show you the result of a flail left chest 5 years ago. Ribs 2-7 were shattered. Surgeon used an abdominal muscle to support the repair, prolly the oblique & must have attached it to scapula. After a few years of numbness all around there, I discovered that I could make the scar jump by tightening my abs. I can make a "smiley face" under my arm, it's weird.
Could u please do a video on marfan syndrome? I already know about it because I have it, but u explain things so easily that I understand things about the body that normally go over my head.
Can we acknowledge what most of us viewers take for granted in these videos: the fact this gentleman is an excellent educator? He was born for this very specific task.
some of us are probably on some governments agency watchlist for watching videos and writing comments like that for me it would be GROM or CBŚ. Whats the name of the government agency that have you on their watchlist?
Well if no one can reach the neck why should it be protected? and also their necks a very muscular and strong only bullets could rip through those necks.
That blood choke is crazy. Someone did that to me in juvenile hall, one moment I was fighting to get loose from his arm and all of a sudden I woke up all confused with drool all over my sweatshirt
That's a pressure point in wing chun kung fu, or dim-dak(touch of death). Essentially, If you are well trained and if you apply enough force to it, you can easily kill the human being with it no matter how strong it is. Bruce Lee knew all these, as well his teacher of it Ip Man. But many people today are like slow Poke Rodriguez: "he packs a guUn" 😂
When you say “in biology, sacrifices must be made” is really a restatement of a key concept in all areas of engineering - trade-offs. Every design, every project, have inherently conflicting goals. The best result optimizes the design against the goals. For example: strength versus weight, speed versus power, time-to-release versus cost. The human body is an optimized product of evolutionary engineering.
designed, engineered & optimized. of course not a product of chance or randomness.. { And in the creation of yourselves and what He disperses of moving creatures are signs for people who are certain [in faith] } -- The Quran 45
I remember learning about some of these areas waaaaaaaay back when I took Martial Arts. I remember one guy got angry that when we were sparring I would crouch down and make myself small so I wouldn't be so open to him....and he said " That's not fair!" Protecting myself isn't fair? Luckily I didn't see him around more than once. One thing we were taught by the instructor though was to never approach someone you may get into a confrontation with head on...exposing your middle to them...approach slightly turned away so you're not a big target saying, " HERE I AM! " Learn to protect your vulnerable parts....take self defense classes. It's smart.
“Hey! Look at my belly!” Love your informative videos. Do you have any cadavers that had IBS? Could you explain that process please? Keep up the great work your guys are doing. Good teaching.
As a person that's been stabbed. This is really cool to see. It explains why after the puncture, the area was tight. This was the omentum trying to seal the wound. That's fascinating af🤓
Perfect balance of clear exposition and technical terms. The enthusiasm helps. This channel is a must for anyone interested in human anatomy, and enjoyable too.
When my appendix ruptured, my omentum managed to wrap itself around the infected area and newly formed abscess, protecting my vital organs, keeping me alive just long enough until I was able to have an emergency appendectomy. I didn't believe it when my surgeon told me, but this cleared up the mystery on how it did that. Thanks!
Being able to use our hands is better for our protection than having our necks, groin and belly directed to the ground. Spears, sticks, bats, punches and firearms would not be possible without this shift ☺️
Intelligence Dexterity a long life span and sociality are important. You need intelligence to create something like a gun you need dexterity to use it and lifespan and socialization spread the knowledge.
Human warriors for thousands of years knew about these 3 damage points, and that’s why even lightly armored foot soldiers had neck braces, abdominal armor and thigh greaves. That helps!
After a catheterization, my father picked up his overweight dog and started bleeding internally. He rushed back to the ER. The bruise went down to his knee. Thank you for these videos - I'm fascinated!!
12:41 I can attest to the liver being a weakness...I fell on the end of a bike handle when I was 14 and got what the ED doctor called a grade 3 liver laceration - basically a baseball-sized hematoma, but thankfully no uncontrolled bleeding and no damage to any of the other delicate organs in that area. But man, those first few minutes after it happened were filled with an absolutely catastrophic amount of pain, and the only reason I wasn't screaming bloody murder was because I could barely breathe.
Good lord. I’ve never had an injury to my liver that bad but my kid landed right on my liver when I was laying on my back once and I couldn’t breathe because the pain was so intense. In some ways we are very fragile creatures but in other ways, we are the most resilient creature on Earth
In the liver was it tore, my daughter had a Stage 5 liver laceration, I'm trying to find out was the liver torn away? The pictures I look I can't tell. She died but I'm trying to figure out what it look like.
As a female MMA fighter. I got punched in the liver and instantly collapsed into a ball with the worst pain in my entire life. Also I got choked out once. I passed out within 6 seconds. The move is called a rear naked choke. Your videos are the best on UA-cam thank you very much!
Chief Jay Strongbow called it a Sleeper Hold. Sgt. Slaughter called it a Cobra Clutch. Now it's a Rear Naked Choke. Do it right and it's a fight ender. Do it wrong and it's called homicide.
Lol my cat blood choked me once. I was lying in bed on my back, almost asleep, and my cat (he’s a big boi, like twenty-five pounds) jumps up and lands on my neck. Paws find my carotid and he stands there, leaning down to sniff my face. I felt the strength drain from every muscle in my body before I could move him… it was weird. Thankfully he stepped off before I passed out so I didn’t die by cat lol
Love these videos inspired me to donate my body to medical science... I have several rare illnesses. Great feeling knowing when i die people can learn about my condions and possibly help lots of people x
My mother passed at the age of 59 and donated her body to have her chronic conditions studied. We were at peace knowing her struggles, trials, & tribulations would not be in vein and would contribute to research. I had decided to donate my body through the same company until I got the letter back about how exactly her body was used. Essentially she got "parted out" and used for things like EMT training rather than actual research on her conditions. Though I know many fields can benefit from these beautiful donations, I was and still am a bit heartbroken since she was told that she would be used for actual anatomical research which was her true desire. As you search for universities or donation programs to donate to, PLEASE do your homework. I'm still happy to donate this shell when my soul departs but I'm being a lot more cautious with what program ends up with my donation.
@@dodi1205jb wow so sorry about your mum 🥺 definitely something to think about. As i would want my body used for medical research for the rare illnesses i have x
The reason humans can afford to have such anatomical vulnerabilities, is that we are inherently cooperative and social. We don't have to defend ourselves from predators because of how we manage our environment. We don't need thick fur because we wear clothes and live in houses. People need to realise how interconnected and social we are by nature. Maybe it would allow them to be better people if they knew it.
Humans did not shed fur and stopped being vulnerable to predators because we invented clothes and houses or were anymore social than other species... first humans stood upright to run faster and shed fur to sweat more..then modified hands for better dexterity to throw weapons. still we were getting our asses kicked by predators. most evolution had already happened by then, giving us speed and better cooling. brain developement and language came much later into the picture
I use to think I am antisocial and when the lockdown happen I realised that that ain't true infact that ain't true for almost every single person, the truth is we love socializing and some people start thinking that they don't, it's cause they've had a bad company/experience with someone etc, but one you take away every form of social interactions we become depressed, frustrated, angry, sad and what not.
We could have such vulnerabilities I feel partly because of our social aspect and strength in numbers but you can't undermine our offensive capabilities. We didn't need crazy defense because over time we just developed and utilized all sorts of offensive tools and traps. Even small groups of people were able to take down giant powerful animals they wouldn't usually stand a chance against with spears, let alone the far more advanced weapons we kept creating
Well-done and fascinating video. I learned so much! I’ve had several hip operations, so I found your explanation of some of the nearby structures really interesting.
“Hey, look at my neck, look at my abdomen, look at my groin!!” Is a great line, and I’m stealing it. Seriously, though, thank you immensely for your extraordinary work. The information your channel provides is an example of the very best the internet has to offer to make the world a better place for everyone. You respectful and unassuming demeanor is exemplary, and the scripts are clearly crafted and delivered with care. Bravo, sir, and again, thank you.
Please tell me why I started to read that line to the tune of Ariana Grande’s “7 Rings.” (The part where she says, “Look at my neck. Look at my jet. Ain’t got enough money to pay me respect.”) 😂
It's great that there is no tacky background music in these videos... Your videos are interesting and stimulating enough on their own. Keep up the good work!
@@westonwheeler2311 so, I’m gonna be pedantic, but: A stab kills pretty quickly or not at all. Clogged arteries take decades. Now, unless someone is expecting to be shot or stabbed, extra weight isn’t very helpful (and even having “too much” muscle can leave someone with an obese BMI lol). A series of tests on this, most famous of which was done by the Mythbusters team, in which simulated “human” muscle and simulated “human” fat were shot and stabbed. Fat and muscle were equally “protective” to damage from killing weapons. That said, protective is in quotes because, iirc, the tests indicated lethality was not very significantly hampered by a few inches of extra fat/muscle, when it came to most of the weapons they tried. Anyway, a larger person, muscular or fat-wise, is probably slightly more resistant to significant stab wounds… to the abdomen. People shouldn’t have to live expecting to get stabbed, so going the “stab resistant, clogged-artery” stance has grave future concern, but should I get stabbed in the abdomen, I hope I have some sort of protective layer there, either way. I don’t live life like I’m expecting a shank, so for that, I say, thank fuck.
I cannot understand why some intelligent people cannot accept the theory of evolution. It’s only necessary to accept that the physiology of all lining things share so many basic organs, each adapted for a given species. But all traceable back to a common ancestor.
I have Dish Network TV at home. I have not checked for some time but I used to watch Med School classes from the University of Washington. I have always been a science nerd so I love this stuff. I have worked in a large hospital for over 20 years and just watched this while I ate lunch. Us hospital people are sick.
20:14 This description is spot on. One day in highschool government, I was very bored so I was compressing my carotid artery (don't ask, I was VERY bored). After a couple seconds my vision starts going dark so I release. I do this a couple more times until I accidentally push it too far and the next thing I know I have a bad headache and am lifting my head from my desk while the whole class stares at me. Apparently I had completely lost consciousness, and once gravity took over my face slammed into my desk, startling the whole class. I did not enjoy trying to explain away what had happened to my teacher...
I never realized the liver was so huge. I would LOVE to see a video about organ donation and specifically partial liver donations from a living donor. My cousin received a triple organ transplant in 2020 and it saved his life despite very low survival odds.
Liver can heal it self, somewhat. But, you can still destroy it. Drug abuse is the worst thing. It doesnt have to be abuse either. I felt my liver, i felt it hurt , and it felt hard, when i got some cancer medisine. Not strange,it IS poison. After this, i had to live like a nun, and that mean also eat food like a non. No fat,no sugar, no taste, and the liver slowly repared itself ) And then alcohol can also kill the liver, but it takes some times... And yes, i agree, i know a bit about the body, but i dodnt realize that size was normal. Its much bigger than i thought. Huge,actually. I thought the heart was big,but thats small, compared to liver....
My first 4 babies were completely natural, Unmedicated births. Awesome! Baby number 5 needed an emergent c section though, and when they sutured me up, they sutured my inguinal nerve. If anyone understands that, you know I was left in unexplainable pain, could pick up my 4lb baby, couldn’t sit up, or walk, etc and had to go back into surgery 4 days later to have my incisions re-opened, all stitches in all layers removed, and re-closed. 10 yrs later I still have lingering pain!
God Bless that’s a painful mistake. I’m a retired Neonatal RN who basically did the baby care the baby during a C/S deliveries and difficult V deliveries. I really don’t think men could withstand some of the things that can happen pain wise. Just the process of mid to late pregnancy causes the pubis to gradually fracture so that the pelvic outlet can enlarge to fit a baby head through. It’s pretty amazing.
The 3 weaknesses that I've found: 1. A linear joint (the knee) placed between two circular joints (ankle and hip,) 2. The esophagus (a relatively unimportant tube) behind the vulnerable, anterior trachea (blockage=death within minutes,) and 3. For women, placing the play ground next to the sewage treatment plant.
To build off of the mobility vs. stability concept you discussed, these weaknesses can be protected by the high level of mobility of the shoulder. As bipeds, our shoulders are very mobile and can be moved quickly and accurately to protect our groin, abdomen, and neck. For some people who have trained it, the hips can be used similarly to move the thighs and legs to protect these areas, though likely with less mobility, speed, and accuracy.
I love this channel so much! you guys are so amazing...am learning a lot about our body and its parts and functions because of you...keep up and God bless your works
That’s another reason misuse of painkillers can be dangerous. Your body uses pain to get you to stop doing something that is hurting you or causing damage but if you’re taking a pain killer you risk wear and tear on your body you otherwise wouldn’t have tolerated.
@@adamlogan41 So glad that someone else recognizes this. When I see people popping pills or voluntarily taking several regular meds instead of making changes so that the pain goes away? It's frustrating. Then, they ask me what meds I take. I don't even keep Tylenol in the house. When I experience pain or discomfort, I change what I'm doing that is causing the pain. A woman I have known for most of my life, prided herself on never sleeping very much. She drove on road trips, 18 - 24 hours straight, then, she would take a cold shower, keep going. I was very afraid for her. As a child I thought she was superwoman because she never slept much taking naps for 10 - 20 minutes here and there. As sad as this feels for me, she has started to have seizures. I had hoped she would slow down. Nope. She started taking meds instead of slowing down. She has had 2 mini strokes recently. So sad.
One example for me was I pulled something in my leg a few months back that slowly recovered. I just had surgery to remove my wisdoms and was given some stronger pain killers (one of which kept trying to knock me out a lot which was good cause it helped keep me semi sedated). The reason it was good was because I noticed that mild pain in my leg was gone and if I had more energy I probably would have used it more (it not hurting made me forget to baby it). Once my pain med course ended I felt that pain back but more than it had been because I was probably a bit rough with it and set its healing back a bit more. Makes me think they make strong pain meds make you drowsy on purpose.
@@FreeSpirit47 unfortunately for some of us, there's apparently nothing to be done, or nothing that outweighs the risk of doing it. Doctors aren't sure for me, but it seems like autoimmunity is just super screwing me over, I'm in so much pain and fatigue and seizures. Even if they were certain, the only fix may be basically nuking the immune system, but that comes with a whole host of dangers and especially when we're in the middle of a massive pandemic. So they just give me painkillers and I take what enjoyment from life I can 😕 Hopefully they'll get better treatments one day, but in the meantime painkillers are all some of us can do 😞
I agree... Beautifully presented. If I may make one suggestion it would be to present the cadaver more clearly ie how it is lying- on its back or side etc, so it will be easier to understand where the structures are. I am especially referring to the neck part. Otherwise an excellent presentation! Pity you weren't around when I was studying anatomy some 50 years ago!
This video basically sounds nearly identical to the physiology and anatomy run down I received in some of my military training on how to quickly and efficiently put a serious hurting on someone. We also got to do more than discuss the matter, we got to put it into practice on ourselves and others and those really are some of the top exploitable weaknesses on the human body. I'm always amazed by the fact that we (humans) are literally one of the weakest species on earth. We have poor natural weaponry, poor natural protection from the elements, a weak and exposed skeletal system, nervous system and both air and circulatory systems. We have sensitive immune systems, our skin is one of the weakest hides to protect a biological structure... we have the weakest claws, the weakest jaws, horrible eyesight, horrible hearing, horrible sense of smell and we are slow, clumsy, non athletic by comparison to other predators, we have one of the weakest muscular systems and we are absolutely and unavoidably vulnerable and defenseless for years after the day of our birth. Without the complete and extensive care of a grown member of our species, we would perish within a few days of being born... yet, in spite of all this, we are the planet's top alpha predator because of our intelligence and ability to craft tools. Without our brain and our intellectual capacities, we would be one of the easiest prey on earth... even cattle, sheep and house pets would be above us in the food chain. I find this truth somewhat displeasing and ironic beyond comprehension, but I'm glad I'm not at the lower levels of nature's food chain... there life is far more harsh and unforgiving than we could probably ever truly comprehend.
Very well said! Our powerful brains overcome our physical limitations! What other animals could create a smartphone and a UA-cam app??? Certainly not my cat Mr. Whiskers!
@@AceNinja2112 lol, I don't know but I'm pretty sure I've met humans that were less intelligent than a cat... so maybe Mr. Whiskers has the upper hand on a few humans out there.
I'll agree on most of it, but non-athletic isn't really true. Yes, a lot of other animals are faster, but in terms of intense sustained efforts, very few can compete. A human runner is completely unable to sprint at 120kmh, sure, but try getting a leopard to sustain just 12kmh and it's going to overheat and fatigue fairly soon. A reasonably fit (i. e. not succumbed to modern amenities) human can keep this up for many hours each day, every day no problem. The reason is that not only are our bodies remarkably efficient at converting chemical energy from food into motion, but also that we are able to efficiently store excess energy for easy access and refuel during exercise, as well as reliably get rid of excess heat and other waste products. That combination is rather unique to our branch of the evolutionary tree. Of course, if you add engineering on top of that, you might end up sustaining 50kmh on a bike - that's impressive by any standard, though maybe not entirely fair for comparison purposes...
@@Will-tm5bj yes, but it was not done 1 on 1 buddy! Humans did that by using large groups of humans or by using hunting dogs. If we go 1 on 1, toe to toe with a healthy and even many unhealthy wild animals to see who will athletically outlast the other, we are going to lose over 99% of the time... and that's speaking about a 1 on 1 with a healthy and athletically fit person. Maybe years in the past, when people didn't have television, the internet, remote controls, vehicles and all the easy life amenities that we have in modern times, people in general might have had a decent overall level of fitness, but today you would be lucky to find a group of Americans who could all run full speed for two city blocks. Obesity, heart disease, diabetes and other unhealthy lifestyle ailments are at an all time high, so yes "unathletic" is quite a fitting description. But even athletic humans are still unathletic by comparison to pretty much all wild alpha predators and that is the main point of my initial comment and it happens to be absolutely correct.
I'm still in awe of how much we can learn from the internet today...From back when there weren't any cellphones..to now...when all knowledge of the human race is at anyone's fingertips, I'm simply in awe. And I find it humblig
It always amazes me the number of people who don't want to learn new things. All the information of man kind at the tip of your fingers and people can't even learn how to change a tire.
Thats a bit ironic though, internet may be globally avaiable for everyone, yet there are still many obstacles that prevent the use of its knowledge. Most of my family and friends only knows spanish, not english. So they would still be unable to learn the way I did from this video. Its a bit sad.
I cannot praise this channel enough ! The enthusiasm and passion for the human body , as well as the details contained WITHIN the relaying of the information - it’s all amazing and extremely contagious !!
Hats of to these people, this channel, this video, this content, but hats off to those humans also whose organs have been used for providing us great scientific knowledge. 👏👏👏
When I was a kid, I was riding a horse that bucked and reared and threw me. When I landed, I broke my clavicle. Thing is, I can't remember being thrown or hitting the ground. Years later I was watching Mike Tyson fight, and thinking, you can't knock this guy out because he has such a thick neck! Then it occurred to me, back when I was on the horse, I passed out while I was still in the saddle, not from the pain of the fracture as I hit the ground. The way pitbulls and other animals shake their prey would have the same effect - it would cause their prey to pass out and become defenseless. It's merciful, really.
Oof. Horse falls can be pretty bad... I've been very lucky not have broken anything falling yet. I'm sure it'll happen eventually. My worst one was when I was riding my neighbor's horse and the poor thing got stung by a wasp. Perfectly understandable why he started crow-hopping. Unfortunately, since I was riding bareback, I had nothing to hold onto, and thus got an impromptu flying lesson. Double unfortunately, the lesson didn't stick and gravity took over. 😂 Random fun fact: horses don't have clavicles!
10:00 Animals can even use this to communicate. In dogs it can show submissions and trust, and cats can show their owner that they trust them by rolling on their back and exposing their belly. They are saying, "Hey look. Here is a venerable part of my body. I know you won't hurt me. In fact, I'll even let you touch me here.""
Your videos are extremely helpful for me to understand anatomy better. Thank you so much. The fact that we decided to “walk around” exposing our vulnerable most parts, to me is an act of defiance to all dangers around us, we started showing we are pretty brave.
Many of us watching this video are making a mental note of "punch the liver" and "punch the hyoid bone" if we're ever attacked. Putting an assailant in a headlock is a good one if you have the opportunity and the strength. Thanks for the fascinating lesson.
@@toku_u fun fact part 2: the human body isn't very efficient at using the 21% oxygen of the atmosphere. It's somewhere around 10 to 12% of that which is why mouth to mouth (CPR) works. Only need 12 to 16% of that 21% to sustain life
all design implies trade off - I cannot take any criticism of bodily 'flaws' seriously unless the person has already produced an improved design. And I am not my genes, and neither are you - anyone can live a successful life despite not breeding - mind over matter, spirit above biology (also, please look up 'reification')
@@MyMy-tv7fd genetic suicide? How is that successful. You are alive because someone gave birth to you lol. That is the purpose of life and all living things. You can change how you define success because that is a social construct, but you cannot deny that reproduction is the purpose of life and failure to do so, is contrary to that. If we believe what you thought, then life would not even exist, we would all be non-existent. Its okay to be a failure in that purpose because there are enough people to pick up the slack.
I love your videos, and the way you explain the information. I'm glad you are making them. I've always being intrigued by how perfect our bodies were created and even in death we still can see the perfect structure of it. Please don't stop making them. If was able to study anatomy of the body, I would like to have teachers like you. You guys are doing exelent job. Thank you!
I can attest to how painful a liver punch is. I was a kid and the neighbor kid and I were fighting over a pretty girl lol (4th grade stuff). He punched me in the stomach but hit my liver and I dropped to the ground. I remember there being those little white flowers that grow in the grass with the clovers in like the month of June. They were all over the ground and after I dropped, I picked one. (Weird total-recall memory, sorry!) The pain was very intense and it'll virtually paralyze you! 😣😩😫😵
16:38 I have a friend who is a veteran soldier from an elite unit of the Colombian army and he has a really shocking scar all around the front of his neck, it happened that he was mugged by a group of thieves, one of them take him from the back but he was resisting so much that the criminal reach the conclusion that the better option was to just kill him, so he take his knife a tried to cut the frontal area of my friend's neck from side to side in a straight line, so he caused this big damage to his neck basically a mortal wound in any person. My friend walked by himself to the hospital and the paramedics couldn´t believe their on eyes, he was not only perfectly conscious, but also even if he had a deep looking wound in his neck, he wasn't bleeding that much, obviously there were scary looking amounts of blood around his neck, however he wasn't bleeding to death, he wasn't in risk of dying inmediately, he just needed to close the wound and a good disinfection. At that time my friend was in peak physical condition and had a lot of muscle, according to the doctors, he survived thanks to some luck and because the muscles around his neck were thick enough to protect vital parts of his neck from the cut, it is important to notice that he was not a bodybuilder but a person subject to daily basis extreme physical activity, like carrying around a lot of weight in equipment, carrying other people and weapons from one place to other just for daily normal training, hours of functional exercises and so on. So I was thinking that probably our ancestors who had to endure a lot of physical activity every day had a lot of really tough muscles which could partially make up for part of the weakness mentioned in the video.
The attack was too fast, my friend could only recognize a couple of them, at the moment he was more worried about his wound than them, so they go away never to be seen again (not like he feels like risking his life to find them), so he never take revenge on them, but that kind of people always ends in jail or death at the side of the road, it is likely that this is what happened to them, they died like garbage in some sad and lonely dark corner.
im so happy i found this channel, im a biology teacher (so not much of a specialist) and im learning so many things to make my lessons that much more intressting!
Great video...I have often wondered at how we survived, in early periods, as a species with so many "Soft Spots"...and seriously vulnerable areas to the human condition.
I would imagine that having so many natural disabilities is the reason we have such large and complex brains. The adaptation to compensate for the natural weaknesses in our structure is enough awareness and memory to be able to create protective measures from the surrounding environment. Thank you for sharing your knowledge. It makes our lives richer.
It's a good thought, but actually does not make much sense from an evolutionary perspective, which is why I currently do not believe humans evolved. You said adaption to 'compensate' for 'natural weaknesses'! Having to 'adapt' in order to 'compensate' for 'natural weaknesses' suggests we evolved with physical weaknesses and have had to adapt to compensate for them with, which does equate to evolution. Weaknesses almost always result in death, for example, millions of people area live today with eyesight so poor, they would have been eaten, or fallen off a cliff to an early death a million years ago. The only reason so many people with bad eyesight are alive today despite that weakness is because of modern science. Evolution should give rise to better adaptations, to make the creature stronger, not create weaknesses that have to be compensated for. As a note, Neanderthals actually had bigger brains than we humans do by the way, as well as very few of our weaknesses, so we are a step backwards in evolutionary terms. We had no reason to lose a fur coat, the benefits of fur far out weight the negatives. Secondly, humans do not have good protective measures at all, most humans are useless in a fight and have to be trained how to go into battle. Put the average Joe in a UFC cage and the guy would be kicked to the ground, chocked or knocked out in less than 10 seconds. Humans have been at war since time began, but most do not have a natural instinct to be able to win a fight or to protect their vulnerable areas. The point this makes about painful testicles being an evolutionary advantage is ridiculous, evolving with them safely inside an able to cope with that temperature would makes far more sense in evolutionary terms. As it is, a mans most vital organs are swinging around where they can easily get trapped, stung, clawed or bitten off by any predator... Humans have been designed, and weakly so at that!
@@ankyspon1701 I agree with both of you but not all the ideas or context here. I am not saying or implying that I am some master or a real expert. But, perhaps, maybe I have more open-mind look and having more solid perspective and understanding why things are what and why they are... : ) I really appreciated these perspectives : D.
@@ankyspon1701 It makes plenty of sense, but different people have different premises, which is why we don't see logic in certain situations that others have arrived at. We're logical beings, but if you start from a different premise, the conclusion from the logic doesn't make sense. That's why miscommunication, arguments, misunderstandings and fights amongst us are so frequent, especially at work. "Weaknesses almost always result in death" - I think we can all agree that this makes sense even at the present day. "The only reason so many people with bad eyesight are alive today despite that weakness is because of modern science" - I think logical people all agree to this as well. This is modern medicine at work. Modern medicine is a result of our adaptation to be able to identify and understand patterns. That ability is a direct result of our brains. "Evolution should give rise to better adaptations, to make the creature stronger, not create weaknesses that have to be compensated for." - This is easily demonstrated by the world around us. So I think we all agree on this as well? I'm not sure what your assertion is here with this statement. But if you think we're the pinnacle of the evolution of life, we will experience our own mass extinction some day. Many of us will die. Could be anywhere from 60% to 90% of all humans. Could be all of us. Who knows. "As a note, Neanderthals actually had bigger brains than we humans do by the way, as well as very few of our weaknesses, so we are a step backwards in evolutionary terms." - The fact that they no longer exist, despite having larger brains and 'less of our weaknesses' proves your third statement that adaptation gives rise to higher evolved forms. A.K.A. you and I. As my own personal note, bigger is not always better. Bigger is not a reliable metric for excellence and survivability. 'don't judge a book by its cover' comes to mind. "We had no reason to lose a fur coat, the benefits of fur far out weight the negatives." - Many homo-sapiens to this day are extremely hairy. Some peoples' genetics have deleted the need to be hairy and they did not die. As a result the genetics proliferate and propagate - evolution at work before our own eyes. Clothes eliminated the need for excessive body hair as our kind transitioned. We adapted. We took fur from animals to wear. Remember when fur trapping was a big deal back in the hundreds of years ago? Pepperidge farm remembers. "Humans do not have good protective measures at all, most humans are useless in a fight and have to be trained how to go into battle." - It's proven humans possess inherent fight or flight response. Our brains have evolved those mechanisms. The hypothalamus portion of the brain coordinates with the pituitary gland to release survival hormones in stressful situations. This is adrenaline. This day in age humans choose to fight for money or fame or as a substitute for insecurity - but it's not at all necessary to do. Battle is completely different from being cornered by a foe on a one on one survival situation. I would not compare war with a survival situation in any amount of good faith for a rational discussion. "Put the average Joe in a UFC cage and the guy would be kicked to the ground, chocked or knocked out in less than 10 seconds." - This simply furthers the point above. UFC fighters train most their lives on techniques to fight - in order to fight for money, fame or as some form of personal release. This is not a good faith comparison. "Humans have been at war since time began, but most do not have a natural instinct to be able to win a fight or to protect their vulnerable areas." - I'm not sure how you can assert people don't have a natural instinct to be able to fight or protect themselves. Evidence is all around us, you just have to choose to seek it out. Use the big brain. Engage the prefrontal cortex we evolved that Neanderthals didn't have and exercise critical thinking on this particular point. " The point this makes about painful testicles being an evolutionary advantage is ridiculous, evolving with them safely inside an able to cope with that temperature would makes far more sense in evolutionary terms." - I like your logic here. Yes, if I were the creator of the current day human species I would choose this as well. However the physical world around us doesn't allow sperm cells to thrive at the resting body temperature of a human. They cannot survive at 98 degrees. They have to be held 4 degrees lower than 98 degrees. It's critical for the proliferation of the human species. If that's not adaptation, I don't know what is. "Humans have been designed, and weakly so at that!" - If humans were as weak as a species as you say, there would not be over 7.9 billion of us. And further, if we were that weak, we would not have the power to destroy a planet - which is what we're doing right now and have been doing since the industrial revolution. I understand you and love you, fellow human. Respect,
I think its the other way around, we are weak because we sacrifice a lot of energy to power our big brains and we are vulnerable to accommodate using our hands and being bipedal. As it worked out being smart and having the capacity to use complex tools was way better.

My dad died of a massive heart attack and my mom died sitting Indian style. I want to understand how they died, but when I found out I wish I hadn't. Like my dad, having a massive heart attack, basically his arteries around the heart exploded that no matter what attempt at resuscitating would've been fruitless because there was no longer veins to run blood to the heart, with no place to go the blood all pooled under the chest and neck causing it to look purple and bruised And mom dying the way she did sitting, with rigormortas having set in they would have to break her legs to straightnen her out to put her on the stretcher. Yes so . I wish I didn't find out.

When you say “in biology, sacrifices must be made” is really a restatement of a key concept in all areas of engineering - trade-offs. Every design, every project, have inherently conflicting goals. The best result optimizes the design against the goals. For example: strength versus weight, speed versus power, time-to-release versus cost. The human body is an optimized product of evolutionary engineering.

I remember learning about some of these areas waaaaaaaay back when I took Martial Arts. I remember one guy got angry that when we were sparring I would crouch down and make myself small so I wouldn't be so open to him....and he said " That's not fair!" Protecting myself isn't fair? Luckily I didn't see him around more than once. One thing we were taught by the instructor though was to never approach someone you may get into a confrontation with head on...exposing your middle to them...approach slightly turned away so you're not a big target saying, " HERE I AM! " Learn to protect your vulnerable parts....take self defense classes. It's smart.

12:41 I can attest to the liver being a weakness...I fell on the end of a bike handle when I was 14 and got what the ED doctor called a grade 3 liver laceration - basically a baseball-sized hematoma, but thankfully no uncontrolled bleeding and no damage to any of the other delicate organs in that area. But man, those first few minutes after it happened were filled with an absolutely catastrophic amount of pain, and the only reason I wasn't screaming bloody murder was because I could barely breathe.
Can confirm this mate. Had the same and was sure I am not getting up anymore.
I got hit in the balls on a bike after a stunt at 13 or 14 talk about pain. I'm 63 and no I had no problem there. i raise a family as well.
Good lord. I’ve never had an injury to my liver that bad but my kid landed right on my liver when I was laying on my back once and I couldn’t breathe because the pain was so intense. In some ways we are very fragile creatures but in other ways, we are the most resilient creature on Earth

Essentially she got "parted out" and used for things like EMT training rather than actual research on her conditions. Though I know many fields can benefit from these beautiful donations, I was and still am a bit heartbroken since she was told that she would be used for actual anatomical research which was her true desire.

The reason humans can afford to have such anatomical vulnerabilities, is that we are inherently cooperative and social. We don't have to defend ourselves from predators because of how we manage our environment.
We don't need thick fur because we wear clothes and live in houses.
People need to realise how interconnected and social we are by nature. Maybe it would allow them to be better people if they knew it.
Humans did not shed fur and stopped being vulnerable to predators because we invented clothes and houses or were anymore social than other species...
first humans stood upright to run faster and shed fur to sweat more..then modified hands for better dexterity to throw weapons.
still we were getting our asses kicked by predators.
most evolution had already happened by then, giving us speed and better cooling.

@@deepeshjain3753 Well, that's your guess.

@@ashokratan88 We are literally ourselves because of other people around us. It's not always easy, but being a human is amazing!
We could have such vulnerabilities I feel partly because of our social aspect and strength in numbers but you can't undermine our offensive capabilities.

Even small groups of people were able to take down giant powerful animals they wouldn't usually stand a chance against with spears, let alone the far more advanced weapons we kept creating

A stab kills pretty quickly or not at all. Clogged arteries take decades.
Now, unless someone is expecting to be shot or stabbed, extra weight isn’t very helpful (and even having “too much” muscle can leave someone with an obese BMI lol).
A series of tests on this, most famous of which was done by the Mythbusters team, in which simulated “human” muscle and simulated “human” fat were shot and stabbed.
Fat and muscle were equally “protective” to damage from killing weapons. That said, protective is in quotes because, iirc, the tests indicated lethality was not very significantly hampered by a few inches of extra fat/muscle, when it came to most of the weapons they tried.
Anyway, a larger person, muscular or fat-wise, is probably slightly more resistant to significant stab wounds… to the abdomen.
People shouldn’t have to live expecting to get stabbed, so going the “stab resistant, clogged-artery” stance has grave future concern, but should I get stabbed in the abdomen, I hope I have some sort of protective layer there, either way.
I don’t live life like I’m expecting a shank, so for that, I say, thank fuck.

The 3 weaknesses that I've found: 1. A linear joint (the knee) placed between two circular joints (ankle and hip,) 2.

What a wonderful return to my A&P class in nursing school. Surprised how much I could still name. And I’m retired at 67. 40+ years as an RN.
To build off of the mobility vs. stability concept you discussed, these weaknesses can be protected by the high level of mobility of the shoulder. As bipeds, our shoulders are very mobile and can be moved quickly and accurately to protect our groin, abdomen, and neck. For some people who have trained it, the hips can be used similarly to move the thighs and legs to protect these areas, though likely with less mobility, speed, and accuracy.

I love this channel so much! you guys are so amazing...am learning a lot about our body and its parts and functions because of you...keep up and God bless your works
I never thought about sensitivity to pain actually being a positive for preservation. It tells us what's important. That makes a ton of sense.
That’s another reason misuse of painkillers can be dangerous. Your body uses pain to get you to stop doing something that is hurting you or causing damage but if you’re taking a pain killer you risk wear and tear on your body you otherwise wouldn’t have tolerated.
@@adamlogan41 So glad that someone else recognizes this. When I see people popping pills or voluntarily taking several regular meds instead of making changes so that the pain goes away? It's frustrating.
Then, they ask me what meds I take. I don't even keep Tylenol in the house. When I experience pain or discomfort, I change what I'm doing that is causing the pain.
A woman I have known for most of my life, prided herself on never sleeping very much. She drove on road trips, 18 - 24 hours straight, then, she would take a cold shower, keep going. I was very afraid for her.
As a child I thought she was superwoman because she never slept much taking naps for 10 - 20 minutes here and there.
As sad as this feels for me, she has started to have seizures. I had hoped she would slow down. Nope. She started taking meds instead of slowing down. She has had 2 mini strokes recently. So sad.
One example for me was I pulled something in my leg a few months back that slowly recovered. I just had surgery to remove my wisdoms and was given some stronger pain killers (one of which kept trying to knock me out a lot which was good cause it helped keep me semi sedated). The reason it was good was because I noticed that mild pain in my leg was gone and if I had more energy I probably would have used it more (it not hurting made me forget to baby it). Once my pain med course ended I felt that pain back but more than it had been because I was probably a bit rough with it and set its healing back a bit more. Makes me think they make strong pain meds make you drowsy on purpose.
@@FreeSpirit47 same and I only take Tylenol if I know I have growth pains or headaches but I never like to take them for anything else
@@FreeSpirit47 unfortunately for some of us, there's apparently nothing to be done, or nothing that outweighs the risk of doing it. Doctors aren't sure for me, but it seems like autoimmunity is just super screwing me over, I'm in so much pain and fatigue and seizures. Even if they were certain, the only fix may be basically nuking the immune system, but that comes with a whole host of dangers and especially when we're in the middle of a massive pandemic.
So they just give me painkillers and I take what enjoyment from life I can 😕 Hopefully they'll get better treatments one day, but in the meantime painkillers are all some of us can do 😞
This guy is amazing. His knowledge is so extensive and his ability to teach it without missing a beat is mind-boggling.
Is he a doctor?
I agree... Beautifully presented. If I may make one suggestion it would be to present the cadaver more clearly ie how it is lying- on its back or side etc, so it will be easier to understand where the structures are. I am especially referring to the neck part. Otherwise an excellent presentation! Pity you weren't around when I was studying anatomy some 50 years ago!
This video basically sounds nearly identical to the physiology and anatomy run down I received in some of my military training on how to quickly and efficiently put a serious hurting on someone. We also got to do more than discuss the matter, we got to put it into practice on ourselves and others and those really are some of the top exploitable weaknesses on the human body. I'm always amazed by the fact that we (humans) are literally one of the weakest species on earth. We have poor natural weaponry, poor natural protection from the elements, a weak and exposed skeletal system, nervous system and both air and circulatory systems. We have sensitive immune systems, our skin is one of the weakest hides to protect a biological structure... we have the weakest claws, the weakest jaws, horrible eyesight, horrible hearing, horrible sense of smell and we are slow, clumsy, non athletic by comparison to other predators, we have one of the weakest muscular systems and we are absolutely and unavoidably vulnerable and defenseless for years after the day of our birth. Without the complete and extensive care of a grown member of our species, we would perish within a few days of being born... yet, in spite of all this, we are the planet's top alpha predator because of our intelligence and ability to craft tools. Without our brain and our intellectual capacities, we would be one of the easiest prey on earth... even cattle, sheep and house pets would be above us in the food chain. I find this truth somewhat displeasing and ironic beyond comprehension, but I'm glad I'm not at the lower levels of nature's food chain... there life is far more harsh and unforgiving than we could probably ever truly comprehend.
Very well said! Our powerful brains overcome our physical limitations! What other animals could create a smartphone and a UA-cam app??? Certainly not my cat Mr. Whiskers!
@@AceNinja2112 lol, I don't know but I'm pretty sure I've met humans that were less intelligent than a cat... so maybe Mr. Whiskers has the upper hand on a few humans out there.
I'll agree on most of it, but non-athletic isn't really true. Yes, a lot of other animals are faster, but in terms of intense sustained efforts, very few can compete. A human runner is completely unable to sprint at 120kmh, sure, but try getting a leopard to sustain just 12kmh and it's going to overheat and fatigue fairly soon. A reasonably fit (i. e. not succumbed to modern amenities) human can keep this up for many hours each day, every day no problem. The reason is that not only are our bodies remarkably efficient at converting chemical energy from food into motion, but also that we are able to efficiently store excess energy for easy access and refuel during exercise, as well as reliably get rid of excess heat and other waste products. That combination is rather unique to our branch of the evolutionary tree. Of course, if you add engineering on top of that, you might end up sustaining 50kmh on a bike - that's impressive by any standard, though maybe not entirely fair for comparison purposes...
"Non-athletic"
Wait until you find out how people hunted by simply not stopping and running the prey to exhaustion
@@Will-tm5bj yes, but it was not done 1 on 1 buddy! Humans did that by using large groups of humans or by using hunting dogs. If we go 1 on 1, toe to toe with a healthy and even many unhealthy wild animals to see who will athletically outlast the other, we are going to lose over 99% of the time... and that's speaking about a 1 on 1 with a healthy and athletically fit person. Maybe years in the past, when people didn't have television, the internet, remote controls, vehicles and all the easy life amenities that we have in modern times, people in general might have had a decent overall level of fitness, but today you would be lucky to find a group of Americans who could all run full speed for two city blocks. Obesity, heart disease, diabetes and other unhealthy lifestyle ailments are at an all time high, so yes "unathletic" is quite a fitting description. But even athletic humans are still unathletic by comparison to pretty much all wild alpha predators and that is the main point of my initial comment and it happens to be absolutely correct.
By watching this video, I can already feel my protective mechanism kicking in by giving me weird pain from the focused area.
Amazing.
I'm still in awe of how much we can learn from the internet today...From back when there weren't any cellphones..to now...when all knowledge of the human race is at anyone's fingertips, I'm simply in awe. And I find it humblig
along with endless misinformation and tripe..
It always amazes me the number of people who don't want to learn new things. All the information of man kind at the tip of your fingers and people can't even learn how to change a tire.
Thats a bit ironic though, internet may be globally avaiable for everyone, yet there are still many obstacles that prevent the use of its knowledge. Most of my family and friends only knows spanish, not english. So they would still be unable to learn the way I did from this video. Its a bit sad.

18:00 “I think breathing is one of my favorite things to do, honestly.” Priceless!
When I was a kid, I was riding a horse that bucked and reared and threw me. When I landed, I broke my clavicle. Thing is, I can't remember being thrown or hitting the ground. Years later I was watching Mike Tyson fight, and thinking, you can't knock this guy out because he has such a thick neck! Then it occurred to me, back when I was on the horse, I passed out while I was still in the saddle, not from the pain of the fracture as I hit the ground.
The way pitbulls and other animals shake their prey would have the same effect - it would cause their prey to pass out and become defenseless. It's merciful, really.
Oof. Horse falls can be pretty bad... I've been very lucky not have broken anything falling yet. I'm sure it'll happen eventually. My worst one was when I was riding my neighbor's horse and the poor thing got stung by a wasp. Perfectly understandable why he started crow-hopping. Unfortunately, since I was riding bareback, I had nothing to hold onto, and thus got an impromptu flying lesson. Double unfortunately, the lesson didn't stick and gravity took over. 😂
Random fun fact: horses don't have clavicles!

10:00 Animals can even use this to communicate. In dogs it can show submissions and trust, and cats can show their owner that they trust them by rolling on their back and exposing their belly.
They are saying, "Hey look. Here is a venerable part of my body. I know you won't hurt me. In fact, I'll even let you touch me here.""
Some cats show that they trust you *not* to touch them on their tummy by rolling on their back, a lot of them don't seem to like it.
Your videos are extremely helpful for me to understand anatomy better. Thank you so much.
The fact that we decided to “walk around” exposing our vulnerable most parts, to me is an act of defiance to all dangers around us, we started showing we are pretty brave.
Many of us watching this video are making a mental note of "punch the liver" and "punch the hyoid bone" if we're ever attacked. Putting an assailant in a headlock is a good one if you have the opportunity and the strength.
Thanks for the fascinating lesson.

I can attest to how painful a liver punch is. I was a kid and the neighbor kid and I were fighting over a pretty girl lol (4th grade stuff). He punched me in the stomach but hit my liver and I dropped to the ground. I remember there being those little white flowers that grow in the grass with the clovers in like the month of June. They were all over the ground and after I dropped, I picked one. (Weird total-recall memory, sorry!) The pain was very intense and it'll virtually paralyze you! 😣😩😫😵
Try getting hit hard while down on the ground in your solar plexus!!!! Eye-Bulging experience to be SURE!!!😜😵😝
I heard that a trauma protect you by forgetting, maybe it was so painful that your brain colour it with beautiful flower.
Was the fight worth it??
They‘re called Snow-Bells in my country
16:38 I have a friend who is a veteran soldier from an elite unit of the Colombian army and he has a really shocking scar all around the front of his neck, it happened that he was mugged by a group of thieves, one of them take him from the back but he was resisting so much that the criminal reach the conclusion that the better option was to just kill him, so he take his knife a tried to cut the frontal area of my friend's neck from side to side in a straight line, so he caused this big damage to his neck basically a mortal wound in any person. My friend walked by himself to the hospital and the paramedics couldn´t believe their on eyes, he was not only perfectly conscious, but also even if he had a deep looking wound in his neck, he wasn't bleeding that much, obviously there were scary looking amounts of blood around his neck, however he wasn't bleeding to death, he wasn't in risk of dying inmediately, he just needed to close the wound and a good disinfection.
At that time my friend was in peak physical condition and had a lot of muscle, according to the doctors, he survived thanks to some luck and because the muscles around his neck were thick enough to protect vital parts of his neck from the cut, it is important to notice that he was not a bodybuilder but a person subject to daily basis extreme physical activity, like carrying around a lot of weight in equipment, carrying other people and weapons from one place to other just for daily normal training, hours of functional exercises and so on. So I was thinking that probably our ancestors who had to endure a lot of physical activity every day had a lot of really tough muscles which could partially make up for part of the weakness mentioned in the video.
Did he seek revenge on the thieves ?
The attack was too fast, my friend could only recognize a couple of them, at the moment he was more worried about his wound than them, so they go away never to be seen again (not like he feels like risking his life to find them), so he never take revenge on them, but that kind of people always ends in jail or death at the side of the road, it is likely that this is what happened to them, they died like garbage in some sad and lonely dark corner.
im so happy i found this channel, im a biology teacher (so not much of a specialist) and im learning so many things to make my lessons that much more intressting!

bang pd what are you doing here 😳
@@danieeccc since I stepped down from CEO, I have lots of free time haha, so just learning anatomy ;)
I would imagine that having so many natural disabilities is the reason we have such large and complex brains. The adaptation to compensate for the natural weaknesses in our structure is enough awareness and memory to be able to create protective measures from the surrounding environment. Thank you for sharing your knowledge. It makes our lives richer.
It's a good thought, but actually does not make much sense from an evolutionary perspective, which is why I currently do not believe humans evolved. You said adaption to 'compensate' for 'natural weaknesses'! Having to 'adapt' in order to 'compensate' for 'natural weaknesses' suggests we evolved with physical weaknesses and have had to adapt to compensate for them with, which does equate to evolution.
Weaknesses almost always result in death, for example, millions of people area live today with eyesight so poor, they would have been eaten, or fallen off a cliff to an early death a million years ago. The only reason so many people with bad eyesight are alive today despite that weakness is because of modern science. Evolution should give rise to better adaptations, to make the creature stronger, not create weaknesses that have to be compensated for. As a note, Neanderthals actually had bigger brains than we humans do by the way, as well as very few of our weaknesses, so we are a step backwards in evolutionary terms. We had no reason to lose a fur coat, the benefits of fur far out weight the negatives. Secondly, humans do not have good protective measures at all, most humans are useless in a fight and have to be trained how to go into battle. Put the average Joe in a UFC cage and the guy would be kicked to the ground, chocked or knocked out in less than 10 seconds. Humans have been at war since time began, but most do not have a natural instinct to be able to win a fight or to protect their vulnerable areas. The point this makes about painful testicles being an evolutionary advantage is ridiculous, evolving with them safely inside an able to cope with that temperature would makes far more sense in evolutionary terms. As it is, a mans most vital organs are swinging around where they can easily get trapped, stung, clawed or bitten off by any predator... Humans have been designed, and weakly so at that!
@@ankyspon1701 I agree with both of you but not all the ideas or context here. I am not saying or implying that I am some master or a real expert. But, perhaps, maybe I have more open-mind look and having more solid perspective and understanding why things are what and why they are... : ) I really appreciated these perspectives : D.
@@ankyspon1701
It makes plenty of sense, but different people have different premises, which is why we don't see logic in certain situations that others have arrived at. We're logical beings, but if you start from a different premise, the conclusion from the logic doesn't make sense. That's why miscommunication, arguments, misunderstandings and fights amongst us are so frequent, especially at work.
"Weaknesses almost always result in death" - I think we can all agree that this makes sense even at the present day.
"The only reason so many people with bad eyesight are alive today despite that weakness is because of modern science" - I think logical people all agree to this as well. This is modern medicine at work. Modern medicine is a result of our adaptation to be able to identify and understand patterns. That ability is a direct result of our brains.
"Evolution should give rise to better adaptations, to make the creature stronger, not create weaknesses that have to be compensated for." - This is easily demonstrated by the world around us. So I think we all agree on this as well? I'm not sure what your assertion is here with this statement. But if you think we're the pinnacle of the evolution of life, we will experience our own mass extinction some day. Many of us will die. Could be anywhere from 60% to 90% of all humans. Could be all of us. Who knows.
"As a note, Neanderthals actually had bigger brains than we humans do by the way, as well as very few of our weaknesses, so we are a step backwards in evolutionary terms." - The fact that they no longer exist, despite having larger brains and 'less of our weaknesses' proves your third statement that adaptation gives rise to higher evolved forms. A.K.A. you and I. As my own personal note, bigger is not always better. Bigger is not a reliable metric for excellence and survivability. 'don't judge a book by its cover' comes to mind.
"We had no reason to lose a fur coat, the benefits of fur far out weight the negatives." - Many homo-sapiens to this day are extremely hairy. Some peoples' genetics have deleted the need to be hairy and they did not die. As a result the genetics proliferate and propagate - evolution at work before our own eyes. Clothes eliminated the need for excessive body hair as our kind transitioned. We adapted. We took fur from animals to wear. Remember when fur trapping was a big deal back in the hundreds of years ago? Pepperidge farm remembers.
"Humans do not have good protective measures at all, most humans are useless in a fight and have to be trained how to go into battle." - It's proven humans possess inherent fight or flight response. Our brains have evolved those mechanisms. The hypothalamus portion of the brain coordinates with the pituitary gland to release survival hormones in stressful situations. This is adrenaline. This day in age humans choose to fight for money or fame or as a substitute for insecurity - but it's not at all necessary to do. Battle is completely different from being cornered by a foe on a one on one survival situation. I would not compare war with a survival situation in any amount of good faith for a rational discussion.
"Put the average Joe in a UFC cage and the guy would be kicked to the ground, chocked or knocked out in less than 10 seconds." - This simply furthers the point above. UFC fighters train most their lives on techniques to fight - in order to fight for money, fame or as some form of personal release. This is not a good faith comparison.
"Humans have been at war since time began, but most do not have a natural instinct to be able to win a fight or to protect their vulnerable areas." - I'm not sure how you can assert people don't have a natural instinct to be able to fight or protect themselves. Evidence is all around us, you just have to choose to seek it out. Use the big brain. Engage the prefrontal cortex we evolved that Neanderthals didn't have and exercise critical thinking on this particular point.
" The point this makes about painful testicles being an evolutionary advantage is ridiculous, evolving with them safely inside an able to cope with that temperature would makes far more sense in evolutionary terms." - I like your logic here. Yes, if I were the creator of the current day human species I would choose this as well. However the physical world around us doesn't allow sperm cells to thrive at the resting body temperature of a human. They cannot survive at 98 degrees. They have to be held 4 degrees lower than 98 degrees. It's critical for the proliferation of the human species. If that's not adaptation, I don't know what is.
"Humans have been designed, and weakly so at that!" - If humans were as weak as a species as you say, there would not be over 7.9 billion of us. And further, if we were that weak, we would not have the power to destroy a planet - which is what we're doing right now and have been doing since the industrial revolution.
I understand you and love you, fellow human.
Respect,
We got bigger brains eating meat andeven larger by cooking with fire.
I think its the other way around, we are weak because we sacrifice a lot of energy to power our big brains and we are vulnerable to accommodate using our hands and being bipedal. As it worked out being smart and having the capacity to use complex tools was way better.

Brilliant, I love learning how our bodies work, your explanations are spot on. Thank you.
