think of the brain like a muscle, and as if you were to walk for miles you would need to sit or lay to rest your leg muscles, the same when you've been consciously using your brain for hours you need to rest it, that's what sleep does, although your brain never fully rests because it is always regulating the function of the body(heart, lungs etc, etc)

I guess to rejuvinate ourselves because if we didn't sleep we'd collapse from exhaustion. But sleep is an odd thing.

Sleeping allows your body to rest, remove toxins from the day's living, and repair damaged tissues. One reason you feel nicely sleepy after exercise is that your muscle tissues are torn by the excersion, and your body needs to sleep to repair the damage.
