Why Do We Sleep?

Yeah, 8 hours and being younger than 25 pretty much promised good sleep.

THE MUSIC IN THE BACKGROUND IA EXTERMELY ANNOYING.

Because where sleepy

This is great 👍🏻 very goooood great!!!! Yash >:3

But thanks for the heads up on the sleep contact thingymajjghsr!!!!!

Maybe or maybe not, who knows???

That's a good question. Am I really sleeping my life away? You could spend so much time in bed when you... My foot.

Im close to day 3 and i cant Wait for the crazy stuff u talk about. Dont let me hanging m8s

Most guys here sleep so they can dream about Lauren

Watching this at 3am just great.

that girl made very odd facel expressions throughout this video and for some reason it just brought me a lot of happiness

They're gonna fuck.

My brain will force a system shut down whenever I try to stay up super late. I'll be laying in bed waiting for a YT video to load on my phone, and then next thing I know it's 7am and I fell asleep in a weird position.

she is weirdly sexy lol

you dont conserve enough energy while sleeping for it to be worth you get eaten by a lion while not being awake... you conserve as much energy as a piece of toast...

What is going on with this woman's face expressions? Sleep deprivation? Drugs? Nobody knows.

why do we sleep and sleeptalk

fuck these people

I find it annoying when you can't get to sleep when you want to.

Plus we've all heard the lame excuses from our parents "all you need to do is lay down and close your eyes"......yeah. That doesn't work for me.

All you need to know is every person needs to do it otherwise you die.

Cos we get tired. Question answered

My problems with sleep are that I fight it like a young child. I will stay up til I'm so exausted I don't want to move. That's when I start getting ready for bed. Lately my bedtime has been around 5AM and I'll wake up around noon.

Why do you have music, barely could understand you. Would be better without the music.

not for nothing, but,Lauren is extremely attractive!

why some topic is not explained in how stuff works, it would be great if every show have a text reference in how stuff works text based so we can have greater understanding. thanks

So we discovered gravitational waves, invented space shuttles, created the Internet and even manipulated the DNA, but we still don't know why we need to be inactive for approx. one third of our life ? And we still have the audacity to confidently profess the non-existence of God based on the scientific findings of our so called "highly evolved" civilization ?
Interesting..

watching the girls facial expressions is just like a try not to laugh challange

Jealous of Lauren's hair (XD)

What happens if you get too much sleep on a regular basis like more than a year at a time and more than 10 hours per day and year of normal height and weight.?

I just woke up!!! And that woman is tripping me out with all her facial expressions.

gonna sleep :)

She is what I would imagine a Cybernetics synth prototype would be like in real life.

Night before last I woke up after 4 hours of sleep, and wasn't tired for the whole day. The day before that I woke up after 4 hours, only got to sleep again after three hours, and then slept 4 more. Fortunately, last night I slept normally, so it was just a fluke. Though I do have problems with insomnia (unmedicated, it normally takes me about an hour to drift off. With sleep meds it takes half an hour. It's been that way as long as I can remember).

The brain has no "trash". It's stores everything you've ever seen, smelled, heard, felt, every text book you've ever read, every song lyric you've ever heard. Everything, it's in there.

Nice, a channel for the same type of dumb asses that type "where does food go" into google

I read somewhere that a lot of our memories are memories of previous times when we recalled the memory, and not the original memories. what if babies make memories but they don't have the cognitive ability to look back at them so they loose the ability to access them

I just don't get tired very easily

That's Ben from stuff they don't want me to know. Hi ben

hmmm, they really don't know why we sleep....6 wasted minutes and 6 minutes I could have been sleeping

Anyone notice how many facial expressions that woman makes when she listens to him talk?

great information...but their chemistry is cringeworthy

I prefer when only 1 person is explaining stuff

The woman looks kinda like Iggy Isazela
