As someone who gets tired from sleeping too long, I can say this is true.

[jennilocke]

I like to call this phenomenon a sleep hangover.

Why do humans have multiple blood types and are there any other mammals with multiple blood types?

My coworkers and I have concluded that being tired is just part of being an adult.
Sleep too much? Tired.
Don't sleep enough? Tired.
Work too much? Tired.
Take a vacation? Tired.
Exercise? Tired. Don't exercise? Tired.

sometimes I will wake up a half hour till my alarm, so i would fall back asleep, and while i felt a decent awareness before, half hour of extra sleep makes me feel SUPER tired when the alarm goes off.

Question: Why do wet surfaces like fabric or asphalt look dark when wet? I know it's got something to do with it breaking the light in a different way or something but I'd still like to hear Craig tell me :)

Also I've heard of a study where they put people in a living complex with no windows or otherwise natural light and no way of telling time for a couple of weeks (I think) and they could turn their lights on and off and go to sleep and wake up whenever they wanted to see what their natural rhythm would turn out to be without any influence from the outside. Weirdly, most of them supposedly lived in a 25-hour-long day, based on their sleep and wake patterns :)

I really hope that one day one of these videos is just 10seconds long and there is the question then just a "no"

I realized that I haven't watched Mental Floss in almost 2 years. wow. I don't know why. nice to be watching again.

I did a presentation on REM cycles in college, and didn't sleep much the night before. The feedback was that I put them to sleep talking to them about sleep after having not slept.

[Gwenni]

i sleep until my body wants to wake up. and sleep when it wants to sleep. as a person who sleeps with the light on my rhythm is a bit different but i still sleep for at least 9 hours.

[MeSwanne]

oh, thank god, I'm under 18. I was afraid, you were going to take my precious sleep away from me!

[TipsyRiver]

There is this Greek proverb that goes "too much sleep brings drowsiness". Over my years as a student, I've found it to be very true.

[JeremysCrazyMind]

8.5-9.5 hours for teens? I'm lucky if I get 6. School is way too early.

[Exayevie]

I find myself feeling most rested after an absolutely ridiculous ten hours. I wish I didn't need to sleep so much. Or more accurately, I wish I lived on a planet with 30-hour days, so I could regularly sleep for ten and be awake for twenty.

[richardable]

I just got 5 hours sleep to wake up at 7:30 am and I feel great!

"There is something known as the circadian pacemaker. It works by..." Sorry, going to have to stop you there, Craig, because the circadian pacemaker clearly doesn't work.
