Our lives would be different if we didn't need sleep, amirite?
How would it be different and what would you miss? I'd miss dreaming...but if we had enough energy to not sleep...that would be fine with me... Although even a computer wears out by being used ALL the time...so perhaps some down time might be good. I can think of a lot of good things by never having to sleep...not so many bad things...what about you?
