I like to think of sleep abstractly, it not really for our bodies its not so that we can rest and recuperate physically. I like to think its all for our minds, we spend all day receiving information and reacting to it in the moment. Our brains are like sponges absorbing information, and experiences. We need those eight hours just so that we can get through the next day without our head spinning off its axis. We aren't prospering we are just surviving taking it one day at a time, and sometimes even that is too much, so we take naps.
