That should, of course, read "Why can't human beings function without sleep?"

the body repairs and rejuvenates itself during sleep
When we get less sleep (even one hour less) than we need each night, we develop a "sleep debt." If the sleep debt becomes too great, it can lead to problem sleepiness – sleepiness that occurs when you should be awake and alert, that interferes with daily routine and activities, and reduces your ability to function. Even if you do not feel sleepy, the sleep debt can have a powerful negative effect on your daytime performance, thinking, and mood, and cause you to fall asleep at inappropriate and even dangerous times.

I know this answer from my experiences with insomnia and going weeks without any sleep at all.
Sleep helps our bodies refuel, repair, and refresh, kind of like our cars.
So when we don't get the sleep we need, our bodies get worn down, inefficient, and running on an empty tank, so to speak.
To mix these biological truths with my religious beliefs, I think that God made the Earth a nearly perfect sphere and set it spinning on its axis like it is so that at any given time, about half of the Earth would be darkened so that we humans could sleep the 6-10 hours we need.
If you think about it further, it seems more than a coincidence that our bodies need almost the exact same amount of time for sleeping that any given area of the Earth spends in darkness away from the sun.

people need to cool down every so often, once heard about a guy that couldnt sleep in his entire life, he died at age 27-28 around there...
u can function...but with problems for the future, i also think it got to do something with the brain, we only use 2% of it...

the same reason we cant live without chocolate. ehhehehe, i would think because our bodies require time to regenerate and to shut down. our response times and mental clarity (not that i have any mental clarity) get fuzzy when we;re over tired.

When I use to smoke ice I'd be awake for up to 7 nights or longer...
I'm not proud of this mind you :(
