Sleeping more than eight hours a day is good for the health, or is it bad? Sleep is like death. Our eyes are closed, our nervous system is inactive. Our muscles... even our consciousness is not available. It is comparable to death, or am I mistaken?
What happens when we sleep? Is there any difference between sleep, naps, dozes, siestas, or snoozes? Can we stay without sleep for more than twenty-four hours?
