Yes, It Is!
What is Sleep, Exactly?
Well, as near as I understand the science, we really don’t know, exactly. Sleep, that state of being that consumes about one-third of our lives, is a bit of a mystery. We know it provides a physical and mental recharge of sorts, but exactly how that works is still not clear.
There are people who do not sleep at all and they seem no worse for that fact. There are not many of them, but enough that science can confirm there does exist a biological construct that does not need sleep.
