Go to bed! Brain researchers warn that lack of sleep is a public health crisis.

“When you are asleep, it’s the most idiotic of all things: You’re not finding food, not finding a mate. Worse still, you’re vulnerable to predation,” said Matthew Walker, a psychology professor at the University of California at Berkeley. “If there was a chance to shave even 10 percent to 20 percent of that time, Mother Nature would have weeded it out through the process of evolution millions of years ago.”
