Summary
Although we know a lot about sleep, there is no scientific consensus on its function or functions. Its functions, however, must be extraordinarily significant, given that it renders us vulnerable to predators each time it overcomes us. It is involuntary. Everyone must eventually succumb to sleep or die. We must have it as surely as we must have oxygen, food, and water. But we do not know why.
