Technically you don't have to sleep.
Technically you don't have to sleep. Even scientists don't know WHY we need sleep just that if we don't sleep there are certain negative emotional effects on our mind. It's not exactly to regain "energy" because we get energy from eating food, not sleeping. That's why there are people in the world who actually don't need sleep cuz their brains have another way of dealing with the buildup of acids and fatigue. Which is quite cool given that they can maximize their everyday. I think they can sleep if they want to though.
Hahahahahahah.
