My dad used to wake up and pee all the time until it was discovered he had sleep apnea and he started using CPAP. Suddenly he stopped peeing multiple times every night. He was told it's not unusual. RainyDayLady maybe that could help you too?
My grandma purposely goes to sleep at like 11 or midnight so she can be up at 5 or 6. She says if she goes to sleep any sooner than that then she's awake at like 4 🤷♀️
74 here. I only get up early to go pee, then only stay up if the nearby airport has airliners buzzing the house. I CAN NOT nap, just doesn't happen EVER.
Health is obvious involved. It is concepts like this that derive from taking samples from everyone which includes 70% of them being on drugs and not exercising for most of their lives. Especially the ones who are old now. They need to take samples from only healthy humans if they want real information about humans.
With increasing elderly folks remaining full time in the workforce into their 70s, I can assure you that, no, we aren't nodding off! (want us out of the workforce so you, too, can move up to a good job as we vacate them? Support social security and Medicare. We don't work because we enjoy it)
I'm a 78 year old guy, and have slept at least 9 hours most nights since I was in my 20s. Less, and I feel tired when I rise, which is bad when one hasn't done anything yet. Sleeping as much as I do, I've never got the bugs that were going around, only succumbing when issued had broken my routine. It would be an interesting subject for one of your vids: How does sleep affect immunity?
I'm curious, do you exercise regularly? And keep your diet in check(plenty of good fats and micronutrients)? If so that might mean its linked to hormones possibly.
@@michaelruskey2311 other than my sleep, and reasonable (not ideal) eating, i don't do much; little exercise latewly, tho i used toi run and lift weights, and wonder if i still have some edge, despite lazsiness last decade.

Like Hank said it's just a hypothesis of why this trend might have been selected for. However, it's not like they themselves would have to do any fighting. They could just be there to keep watch and wake up the younger folks if needed.
This was a GREAT video. Although I love his relaxed voice in the MicroCosmos, I also really like it when you can hear excitement for a subject shine through like this. Well done. Thank you.
Well, yes, this is a clever insight. It's not that older people sleep less. Or it's harder to stay asleep for very long. We just spread it out during the day. Younger people have jobs and childcare responsibilities and can't spread their sleep out because of this. Young people, have to be ready for work and may be using medication or drugs to get to sleep so they can be ready for work. And do younger people wake up in the night and can't fall asleep again because they are worrying? Yes.
@@polenc7167 Sleeping for 4 hours in the night and 4 later in the day isn't going to have the same results as sleeping 8 hours straight. There's studies in the science of sleep implying this point, so can you really say that by sleeping 4+4 hours, you're sleeping the same amount as someone for example sleeps 7-8 hours straight? In some sense, by spreading out the sleep throughout the day, you will actually be losing sleep.
Look again. The title says "wake up early", and they clear up that they need just as much sleep as anyone else. Nowhere do they say they need less sleep.
The circadian rhythm has 2 points during a 24 hour cycle where the 'sleepiness' hormones build up, to cause you to want to fall asleep. There is one at night, but there is also a smaller peak of sleepiness hormones in the afternoon around 2 o'clock. That's a big part of why people often feel sluggish after lunch. I would guess that the reason older people nod off around midday is because they're actually lacking sleep from the previous night, so when their second 'sleepiness' hormone peak comes up they're less able to resist it so fall asleep when they shouldn't really do so.
I'm only 45, but in the past couple years, I wake up many hours earlier and feel far better with less sleep than I ever did. Sleep quality has improved greatly. I'm now like my morning lark mom rather than her night owl parents. So it definitely seems like there are multiple reasons for the stereotype.
Some of my fondest memories is of my grandmother, up at 5:30 am, sitting in her rocking chair, coffee cup in hand, watching the Rocky and Bullwinkle show.
Yeah, I'm a young guy myself. 21 in a few months. Lost my first good job because waking up at 5:30 in the morning was killing me. You can call me lazy or whatever, but naturally I fall asleep around 2 and wake up at 10.
@@I_Mark_Mills Install f.lux (or something similar) on all your devices so that blue light gets filtered in the evening. Blue light somehow prevents the melatonin from doing its job making you sleepy, so settling for more orange-y light in the evening might help (it does so for me). Go to bed every day at the same time. For me it's 11pm, when then I read a book for about 1 hour before proceeding to sleep until the alarm goes off. Do it this way ALL day, also on weekends, so that your body gets used to it. That's how it works for me. You're not the slave of your sleep cycle; you can train it.
@@Theraot Yes, I've already seen that one. But as long as you don't at least try to adjust your sleep cycle, you can't be sure whether you're a pathological night owl or not, and therefore genetics is just a lame excuse for not trying.
The only reason I get up at 4:00 am is either my bladder or 1 or my 4 dogs bladders says that it's pee o'clock. Happens most nights, somebody's gotta go, but everyone goes right back 2 sleep.
You know, I now feel better about getting up at 3:30 AM. I thought it might simply have been an excuse for my daily afternoon siesta. Now if I could only stay past 8 PM.
Are you sure they sleep less..? Because I work at an assisted living facility and most of the residents go to bed at like 7-9pm and wake up around 5-7am. We have to do 2 hour checks on every resident and hourly checks on residents who require special care. Usually the only ones that are awake during the nights are the ones in the memory care unit (with dementia or Alzheimer’s) but most of them sleep pretty well, or aren’t awake when we go in there every two hours. Idk that’s just my personal experience.
I love the idea of a hunter/gather tribe's seniors serving as their dawn watch, a reason besides protecting seniors because they are repositories of a tribe's historical knowledge and traditions.
The weird thing is, all those people trying to link things to the pineal gland, is actually caused by the thymus gland, and a breakdown of mitochondrial uncoupling protein. Including the buildup of this brain sand. Give them some DHEA or Catalpol+Carnosine(same as Dhea when combined), Metformin, and PDE 3, 4, and 5 inhibitor, then watch it, some signs of aging, and metabolic disorder driven obesity reverse.
@@darkhorseman8263 There's a lot of mythos that the pineal is a doorway to higher dimensions. Therefore the calcification of the pineal is more or less a cataract of the soul in most new ageists mythos. RE:EDIT: Didn't finish last sentence. Twice.
When i had to make adjustments to my life habits about ten years ago , i learned that hormones come in three categories and that our gut flora might contain 30 to 40 different groups and that some of these may interact with our metabolism like a chain reaction. Eating healthy and keeping a regular sleeping schedule was vital for me , but i must admit that my sleep has been interrupted since my puberty (over 30 years ago). I've been waking up 3 times a night for ages and knowing that sleep cycles come in blocks of 90 minutes or so allowed me to better manage this irregularity. Odd part though is that i hardly ever get a nap on the weekends in the afternoon but i often feel drowsy in mid afternoon during the week. Thanks for sharing this info and allowing me to share this insight Hank. And to think of it , i wonder if those brain sand particles wouldn't just be the physical manifestation of memories or if they are a plain simple sign of aging. I know that calcium deposits in the gull bladder are painful and that they aren't a regular phenomenon , for me anyways.
Hello, I'm your daily anecdote. It's true. My sisters and I are now in our 60s and 70s and not a one of us sleeps throughout the night. Today, I arose at 2:48 AM. yesterday, I was up at 4. We now understand our dad's referral to "dead as four o'clock" when citing a time when nothing is going on. The same idea was more poetically put by Bob Dylan in the line "thy ancient, empty streets too dead for dreaming," from Mr. Tamborine Man.
i’m only 28, but when i was at the psychward last year i was slamming my forehead against the walls of my high-observation cell a lot which got blood on the walls sometimes and they did electro convulsive therapy on me for several months after i had stopped living there until i couldn’t handle it anymore so i quit, and now im taking hormone regulation therapy, so... this video explains why my sleep schedule has been 2-10 hours asleep/8-36 hours awake for roughly 6 months!!! EDIT: mister sandman, bring me a dream / put bones in my brain, like i’m your latrine
I'm 71 and this is the most fascinating info on why I wake up between 4:30 and 6:60 in the morning. I will be volunteering for the last shift of the nightly lion/bear/hyena watch.
Kati, you do realise that we are the members of the tribe that that those pisants juvenile delinquents are least likely to miss, because they have yet to realise how much we contribute to the cultural heritage of Our Tribe, and will probably never even appreciate our sacrifice as guardians/ bait/ food/ protection.
That's a good point. He said this can happen as early as 40yr, so if the average lifespan was around 35 then a few people would live to be 40+. I wonder if there were enough people in that age range for that argument to be valid. Anyone knows?
@@jessehudgins6066 Yeah, I agree. The way I see it if you survived adolescence and a childbirth it was "smooth sailing" later. Sure, toothless, arthritic sailing, but still.
I had the same question as you, but indeed at the paleolithic age (according to Wiki), if you passed the age of 15, you were expected to live 54 years in total. Still doesn't fit enough to the theory for me. Maybe the effects were greater back then? I believe it's more like a bug and not a feature.
@@limiv5272 but on the other end, being eaten by Lions or more likely killed from fighting other humans was the other reason for low mortality rates... so if you survived your weapon/child bearing years, you probably had taken injuries that made you unsuitable for those activities, but you still had to prove your Worth to the tribe or you would probably be left behind. so guardianship probably makes sense in this case. the modern popular imagination never has young people in the role of shaman. so extrapolating from that, shaman was probably what younger people trained for for when they couldn't do the young people things. like a retirement job. for me where this theory falls apart is that no one slept in. there was a LOT to do while daylight was available
Thank you!!! Didnt realize this was a question I had until you just answered it - my dad gets up wicked early, and I have started now too in my mid 30s (although some of it is due to chronic pain). 👏
I simply wake up when I'm no longer tired and go to bed when I am, which doesn't necessarily follow a 24h sun cycle. It's actually closer to 28-30h most of the time (up for 18-20, down for 10-12) = sometimes I wake up "early" at 5am and a week later I "oversleep" and get up at 5pm. Kinda weird how that works when one isn't a slave to a clock.
My Father-in-law did this of waking up super early but he also took a daily nap. And had been waking up so very early since he was a young adult. His job required him being there at 5 am the latest 6 am.
One theory for brain sand has to do with excess fluorine in the diet and environment. There's talk in the organic food world about fluorine calcifying the pineal gland, and I know fluorine sure loves reacting with calcium. Chill out, skeptics. I'm not preaching it as Gospel. It's just a novel perspective.
Man In The Hills www.ncbi.nlm.nih.gov/pmc/articles/PMC6017004/ pubmed.ncbi.nlm.nih.gov/11275672/ Here’s a nice quote from the first one: “However, the environmental biohazards may also contribute to its development. One of them is fluoride. It was reported that the pineal gland in goosander concentrates fluoride which is a water pollutant [290]. The level of fluoride in the pineal gland of goosander was 5-fold higher than that it in the brain of the animal. The similar results were observed in the aged human pineal gland. In addition, the high level of fluoride in the human pineal gland is positively related to its calcium accumulation of the gland [291]. Thus, decrease in environmental fluoride pollution may be helpful in delaying or avoiding premature pineal calcification.”
My Grandma has always been an early morning person, rising with or before the sun for most of her adult life. In retirement her sleep cycle has crept back and back, and at 90 she now begins her days at *literally 1 or 2 in the moring.* I wonder which of these potential causes she has going on!
I'm inclined to agree with the sentinel hypothesis. I'm around 70yo and have found my sleep patterns changing with age. I'm still working, but it's a bit weird when you find yourself with your eyes closed at your desk in the middle of the day, yet find yourself alert and thinking a lot at 02:30. I don't worry about it any more than I worried (Not) about being so slow to get going in the a.m in my teens.

@@TheWallsocket The irony is, IIRC, fluoride in tap water, is put there to cause exactly this effect deliberately, because the pineal gland is in the geometric center of the brain, making the physical displacement of the pineal gland by even 1mm is enough to diagnose swelling in specific regions of the brain, and having increased calcium in the pineal, allows such displacement to be visible in a simple CT scan, which takes roughly a minute, rather than a full MRI which can take an hour or more, and cannot be done with implants. The other reason I know of for sodium fluoride in tap water, was, IIRC, that sodium fluoride is a byproduct of certain old types of nuclear reactors, or more accurately, the reaction of certain coolants in the reactor, and was a form of non-nuclear waste, and rather than pay to have it disposed of, found a way to sell their waste, marketing it every which way they could, and that while we nolonger use that type of reactor anywhere, we still have a massive stockpile of sodium fluoride, with nothing else to do with it, and that this is also why it was studied by dentists and is now in toothpaste. And if your curious, I found all this out while researching and debunking the notion that it's in the tap water for mind control, which is just a pile of hot garbage, but I'm uncertain of any of the citations for it. Thank you for finding those citations though.
I tend to miss some of SciShow's videos because of how the thumbnail has that frame which makes it look like the red line on the bottom of videos I previously watched.
That 'elder sentinel' hypothesis sounds a lot like a form of group selection, since such changes in sleep patter are rather unlikely to benefit the individual. Especially so late in their lives. As far as I know, not many scientists are on board with the 'group over individual' idea.
Boiled Water from Dried Bael fruit can help you get a long sleep through the night. The only side effect is a low blood pressure so drink the boiled Bael fruit water in the evening on would do just that but not in during the day as you might faint. That's from my experienced which recommended by physician. I was on sleeping pills and off because of that. But don't drink it too much (not over 700 cc) as you might get dizzy in the morning.
My grandpa was still getting up at 5 am at 89. I always thought it was because he had been a rural route carrier for the post office. Thirty years of getting very early for a very long route. He died a few days short of his 90th birthday.
Literally just finished Hank's book, An Absolutely Remarkable Thing, and had to immediately watch a ScIShow episode so I could give the book a shout out in the comments. Great job Hank!

Can you bring up some of the new reasearch about the use of psychadelics to treat mental health? PS I really wanna know if flouride has anything to do with the calisification of the pineal gland? But I am too lazy to sift through all the research papers. I hope that during my lifetime we'll learn more about the brain and the subconscious. I have some theories of my own. Have a nice day to who ever might be reading this ❤
Marie Domander here’s a better one: www.ncbi.nlm.nih.gov/pmc/articles/PMC6017004/ Here’s a nice quote from it: “However, the environmental biohazards may also contribute to its development.

Thus, decrease in environmental fluoride pollution may be helpful in delaying or avoiding premature pineal calcification.” Three chronic conditions also accelerate it: brain tissue hypoxia, chronic inflammation, and elevated inter-cranial pressure. Keep in mind that some calcification is inevitable as you age, the study goes into that but it’s a long read.
I sleep 6 to 7 hours a day, in bed at 3 AM & up at 9 to 10 AM. I'm 55. When I was a kid, it was 5 hours a night, on average. Rarely felt tired. Now, I need naps mid-day. Some weeks, I'm back to the 5 hour a night sleep pattern (not on purpose, just my rhythm) & it can take a couple weeks to go back to "normal". And this strange-ish pattern is _with_ taking melatonin every night. I hesitate to wonder what my sleep pattern's gonna be like in 10-15 years...
At 66 I do not wake up any earlier than I have to. And if allowed I would naturally sleep until about 9am, which was my natural wake up point in my 20s. I DO want to go to bed earlier than I used to. It does take me target sleep hours + 1 from nodding off to wake up in order to achieve target hours.
The more crucial question scientists should be asking is: Why do old people get up early - and then wait til lunchtime to go queue at the post office, when they've had all goddamn morning to go?
Both my parents are retired and they wake up around the same time I do when I have to get up and go to work around 6am. For the record, I don’t live with them, I just know because they would text me around that hour.
"Even though it's a stereotype, there does appear to be some truth to this." Hank, that's why stereotypes exist at all! There is no "indian cuisine is bland" sterotype or "scishow videos are uninformative" sterotype, after all ;)
Synonymous there are plenty of stereotypes that have no truth what so ever: that blonds are stupid, Irish are drunkards, Hispanics are lazy... perhaps Hank is being overly politically correct but it’s probably a good idea to clarify when one is talking about an actual trait of a group as opposed to one that is only applied to the group by “conventional wisdom” but has no real basis.
@@jpe1 good point. I wasnt really trying to say all stereotypes are accurate, just that it's silly to pretend like they simply pop into existence out of thin air. Usually they start out as truthful, and then overtime are distorted by social forces until you get something like the "blondes are stupid" sterotype. That one in particular probably started out as a "valley girls" are stupid stereotype, which would make it somewhat true as people who embody that persona dont tend to look too positively at the idea of studying. But then an association developed between valley girls and blonde hair, which changed it to the inaccurate version we have today.
Hank, I'm 62 and my sleep schedule is messed up. I stay up all day. Go to sleep at about 11pm. Wake up and stay up around 4am. I get about 5 hours rest per day on average. It sucks.
When I was working. I had to work two full-time jobs to pay bills and not be of very basic needs. One job paying $11.50/hr. The Other From $15 - $20/hr. In the year 2000. I was able to tell myself, "GO TO SLEEP" in my mind and do it. I also told myself when to "Wake - Up!" And did it as we got to the work sight. So the hypothesis of what's going on is off. I say individual choice.
Had moderate insomnia for many years, averaging 4-5 hours of sleep per day. Written five fiction novels in last 11 years, two books on cinema. I wish I could give away and bottle my unquenchable creativity because others might benefit from it❗❗❗❗
1) brain sand -> fossilisation is starting, therefore calling them " fossils " is true. 2) In the cave, they get up early to get the best of the leftovers and they can kick the younger people, who have spent the night protecting the tribe, when they are settling down for a sleep, calling them lazy good-for-nothings and that half the day is over etc. In the middle of the day, while the youngsters are out hunting/gathering they will settle down for a snooze ( people are moving around in the camp to keep predators away ).
Well, I'm older and wake up "with the chickens" and it's been very useful for me to get to my local supermarket at 5:00 am when they open and buy stuff without people around, and for filling Amazon Fresh delivery windows when they open up. Not to mention scoping out financial markets before the trading day opens. So, this phenomenon is actually serving me well now.
QUESTION - Why don’t we ever see nature shows on what Walruses and Elephant seals do with the other 80% of their time when not on shore to mate??

Sleep patterns change as we age. Fetuses sleep almost all the time. Infants sleep most the time. Teens can sleep all day long. Adults sleep less. The elderly sleep less and poorly. Its a natural part of aging and dying. Sleep well.😴

I've never been a good (deep) sleeper. When I had small children it was very useful to be able to wake quickly and be alert. (lions and tigers and bears oh my) But now that I am older, nitetime has become literal torture. Physical pain, constant trips to the bathroom and the inability to just *frickin* fall asleep, make me a grumpy old bat.
I've fought against Insominia my entire life, but now that I'm 49 things are worse. the last two years or so, I can't sleep more than 4 hrs at a time. I'm disabled & retired so I'm able to take a nap later on(sometimes I can fall asleep, sometimes I'm up for 24 hr!) , but I really can't get a cycle down. Sometimes I can fall asleep at 11pn, but next day I may be awake until 4 AM. X___X
Spoiler Alert: It's mostly because of recent history, as when people retire from their career, they have lots of free time and don't stress out as much, so they tend to wake up earlier. Many people discover god and/or spirituality and start praying and meditating daily, hence their third eye opens and decalcifies. True story bros

Am I missing something here, because how could children and the elders defend us from a pride of carnivores?
Like Hank said it's just a hypothesis of why this trend might have been selected for. However, it's not like they themselves would have to do any fighting. They could just be there to keep watch and wake up the younger folks if needed.
You're not supposed to fight the lion, just be vigilant and if needed wake up the young adults so THEY could fight the lion
Their screams of terror will wake the more able-bodied individuals.
A way of getting rid of the weak and sick... plus given the size of an adult it might be enough to satisfy some carnivores.
By yelling "Yo wake up theres a lion!" probably

SciShow: “Older people sleep less”
*Me:* **looking at my grandpa who is sleeping mid-day**
Well, yes, this is a clever insight. It's not that older people sleep less. Or it's harder to stay asleep for very long. We just spread it out during the day. Younger people have jobs and childcare responsibilities and can't spread their sleep out because of this. Young people, have to be ready for work and may be using medication or drugs to get to sleep so they can be ready for work. And do younger people wake up in the night and can't fall asleep again because they are worrying? Yes.
@@polenc7167 Sleeping for 4 hours in the night and 4 later in the day isn't going to have the same results as sleeping 8 hours straight. There's studies in the science of sleep implying this point, so can you really say that by sleeping 4+4 hours, you're sleeping the same amount as someone for example sleeps 7-8 hours straight? In some sense, by spreading out the sleep throughout the day, you will actually be losing sleep.
Look again. The title says "wake up early", and they clear up that they need just as much sleep as anyone else. Nowhere do they say they need less sleep.
The circadian rhythm has 2 points during a 24 hour cycle where the 'sleepiness' hormones build up, to cause you to want to fall asleep. There is one at night, but there is also a smaller peak of sleepiness hormones in the afternoon around 2 o'clock. That's a big part of why people often feel sluggish after lunch.
I would guess that the reason older people nod off around midday is because they're actually lacking sleep from the previous night, so when their second 'sleepiness' hormone peak comes up they're less able to resist it so fall asleep when they shouldn't really do so.
I'm only 45, but in the past couple years, I wake up many hours earlier and feel far better with less sleep than I ever did. Sleep quality has improved greatly. I'm now like my morning lark mom rather than her night owl parents. So it definitely seems like there are multiple reasons for the stereotype.
Some of my fondest memories is of my grandmother, up at 5:30 am, sitting in her rocking chair, coffee cup in hand, watching the Rocky and Bullwinkle show.
Im 27 now... Can we finally stop forcing 14 year olds to wake up at 5:30 to go to school when the sun rises at 9:30?
Yeah, I'm a young guy myself. 21 in a few months. Lost my first good job because waking up at 5:30 in the morning was killing me. You can call me lazy or whatever, but naturally I fall asleep around 2 and wake up at 10.
@@I_Mark_Mills Install f.lux (or something similar) on all your devices so that blue light gets filtered in the evening. Blue light somehow prevents the melatonin from doing its job making you sleepy, so settling for more orange-y light in the evening might help (it does so for me).
Go to bed every day at the same time. For me it's 11pm, when then I read a book for about 1 hour before proceeding to sleep until the alarm goes off. Do it this way ALL day, also on weekends, so that your body gets used to it. That's how it works for me.

You know, I now feel better about getting up at 3:30 AM. I thought it might simply have been an excuse for my daily afternoon siesta. Now if I could only stay past 8 PM.
Have you tried slow release melatonin?
Are you sure they sleep less..? Because I work at an assisted living facility and most of the residents go to bed at like 7-9pm and wake up around 5-7am. We have to do 2 hour checks on every resident and hourly checks on residents who require special care. Usually the only ones that are awake during the nights are the ones in the memory care unit (with dementia or Alzheimer’s) but most of them sleep pretty well, or aren’t awake when we go in there every two hours. Idk that’s just my personal experience.
Man, I love Hank. Don't think I would've ever started watching if not for him
A lot of elderly take day naps too. I wonder how naps further influence their nights rest and body's circadian rhythm.

Gotta decalcify your pineal gland, brah, open your third eye!
Kinda suprised the lack of unironic decalcification comments tbh
The weird thing is, all those people trying to link things to the pineal gland, is actually caused by the thymus gland, and a breakdown of mitochondrial uncoupling protein.
Including the buildup of this brain sand.
Give them some DHEA or Catalpol+Carnosine(same as Dhea when combined), Metformin, and PDE 3, 4, and 5 inhibitor, then watch it, some signs of aging, and metabolic disorder driven obesity reverse.

When i had to make adjustments to my life habits about ten years ago , i learned that hormones come in three categories and that our gut flora might contain 30 to 40 different groups and that some of these may interact with our metabolism like a chain reaction. Eating healthy and keeping a regular sleeping schedule was vital for me , but i must admit that my sleep has been interrupted since my puberty (over 30 years ago). I've been waking up 3 times a night for ages and knowing that sleep cycles come in blocks of 90 minutes or so allowed me to better manage this irregularity. Odd part though is that i hardly ever get a nap on the weekends in the afternoon but i often feel drowsy in mid afternoon during the week. Thanks for sharing this info and allowing me to share this insight Hank. And to think of it , i wonder if those brain sand particles wouldn't just be the physical manifestation of memories or if they are a plain simple sign of aging. I know that calcium deposits in the gull bladder are painful and that they aren't a regular phenomenon , for me anyways.
Cool video, that help shed some light on this issue!
Hello, I'm your daily anecdote. It's true. My sisters and I are now in our 60s and 70s and not a one of us sleeps throughout the night. Today, I arose at 2:48 AM. yesterday, I was up at 4. We now understand our dad's referral to "dead as four o'clock" when citing a time when nothing is going on. The same idea was more poetically put by Bob Dylan in the line "thy ancient, empty streets too dead for dreaming," from Mr. Tamborine Man.
i’m only 28, but when i was at the psychward last year i was slamming my forehead against the walls of my high-observation cell a lot which got blood on the walls sometimes and they did electro convulsive therapy on me for several months after i had stopped living there until i couldn’t handle it anymore so i quit, and now im taking hormone regulation therapy, so... this video explains why my sleep schedule has been 2-10 hours asleep/8-36 hours awake for roughly 6 months!!!
EDIT: mister sandman, bring me a dream / put bones in my brain, like i’m your latrine

How old were grandparent cavemen compared with today's grandparents? I can't see the evolutionary connection?
That's a good point. He said this can happen as early as 40yr, so if the average lifespan was around 35 then a few people would live to be 40+. I wonder if there were enough people in that age range for that argument to be valid. Anyone knows?
Extreme infant mortality rate back then is why average lifespan was so low, if you lived to be 20 you could easily make it to 50 back then
@@jessehudgins6066 Yeah, I agree. The way I see it if you survived adolescence and a childbirth it was "smooth sailing" later. Sure, toothless, arthritic sailing, but still.
I had the same question as you, but indeed at the paleolithic age (according to Wiki), if you passed the age of 15, you were expected to live 54 years in total. Still doesn't fit enough to the theory for me. Maybe the effects were greater back then? I believe it's more like a bug and not a feature.
@@limiv5272 but on the other end, being eaten by Lions or more likely killed from fighting other humans was the other reason for low mortality rates... so if you survived your weapon/child bearing years, you probably had taken injuries that made you unsuitable for those activities, but you still had to prove your Worth to the tribe or you would probably be left behind. so guardianship probably makes sense in this case. the modern popular imagination never has young people in the role of shaman. so extrapolating from that, shaman was probably what younger people trained for for when they couldn't do the young people things. like a retirement job. for me where this theory falls apart is that no one slept in. there was a LOT to do while daylight was available

I simply wake up when I'm no longer tired and go to bed when I am, which doesn't necessarily follow a 24h sun cycle. It's actually closer to 28-30h most of the time (up for 18-20, down for 10-12) = sometimes I wake up "early" at 5am and a week later I "oversleep" and get up at 5pm. Kinda weird how that works when one isn't a slave to a clock.
My Father-in-law did this of waking up super early but he also took a daily nap. And had been waking up so very early since he was a young adult. His job required him being there at 5 am the latest 6 am.

One theory for brain sand has to do with excess fluorine in the diet and environment. There's talk in the organic food world about fluorine calcifying the pineal gland, and I know fluorine sure loves reacting with calcium.

Here’s a nice quote from the first one: “However, the environmental biohazards may also contribute to its development. One of them is fluoride. It was reported that the pineal gland in goosander concentrates fluoride which is a water pollutant [290]. The level of fluoride in the pineal gland of goosander was 5-fold higher than that it in the brain of the animal. The similar results were observed in the aged human pineal gland. In addition, the high level of fluoride in the human pineal gland is positively related to its calcium accumulation of the gland [291]. Thus, decrease in environmental fluoride pollution may be helpful in delaying or avoiding premature pineal calcification.”
My Grandma has always been an early morning person, rising with or before the sun for most of her adult life. In retirement her sleep cycle has crept back and back, and at 90 she now begins her days at *literally 1 or 2 in the moring.* I wonder which of these potential causes she has going on!
What time is she going time bed? I'd imagine somewhere between 7-9? Maybe right in the middle at 8? Does she take naps?

@@TheWallsocket The irony is, IIRC, fluoride in tap water, is put there to cause exactly this effect deliberately, because the pineal gland is in the geometric center of the brain, making the physical displacement of the pineal gland by even 1mm is enough to diagnose swelling in specific regions of the brain, and having increased calcium in the pineal, allows such displacement to be visible in a simple CT scan, which takes roughly a minute, rather than a full MRI which can take an hour or more, and cannot be done with implants.
The other reason I know of for sodium fluoride in tap water, was, IIRC, that sodium fluoride is a byproduct of certain old types of nuclear reactors, or more accurately, the reaction of certain coolants in the reactor, and was a form of non-nuclear waste, and rather than pay to have it disposed of, found a way to sell their waste, marketing it every which way they could, and that while we nolonger use that type of reactor anywhere, we still have a massive stockpile of sodium fluoride, with nothing else to do with it, and that this is also why it was studied by dentists and is now in toothpaste.
And if your curious, I found all this out while researching and debunking the notion that it's in the tap water for mind control, which is just a pile of hot garbage, but I'm uncertain of any of the citations for it. Thank you for finding those citations though.

I tend to miss some of SciShow's videos because of how the thumbnail has that frame which makes it look like the red line on the bottom of videos I previously watched.
That 'elder sentinel' hypothesis sounds a lot like a form of group selection, since such changes in sleep patter are rather unlikely to benefit the individual. Especially so late in their lives. As far as I know, not many scientists are on board with the 'group over individual' idea.

@@jpe1 good point. I wasnt really trying to say all stereotypes are accurate, just that it's silly to pretend like they simply pop into existence out of thin air. Usually they start out as truthful, and then overtime are distorted by social forces until you get something like the "blondes are stupid" sterotype. That one in particular probably started out as a "valley girls" are stupid stereotype, which would make it somewhat true as people who embody that persona dont tend to look too positively at the idea of studying. But then an association developed between valley girls and blonde hair, which changed it to the inaccurate version we have today.

I'm disabled & retired so I'm able to take a nap later on(sometimes I can fall asleep, sometimes I'm up for 24 hr!) , but I really can't get a cycle down. Sometimes I can fall asleep at 11pn, but next day I may be awake until 4 AM.
X___X
Spoiler Alert: It's mostly because of recent history, as when people retire from their career, they have lots of free time and don't stress out as much, so they tend to wake up earlier. Many people discover god and/or spirituality and start praying and meditating daily, hence their third eye opens and decalcifies.

I have Social Pragmatic Communication Disorder (scd) & at times I get confused, even as an adult who has trained to understand most sarcasm, but I worry about the younger audience members who may not have had my level of training or experience... Thank you for the great content, keep up the good work.
Haha! "wee hours", nice pun, you do know about being old!
