  Wow, it's four o'clock in the morning, and I am still up. I got about ten hours sleep last night, so that has probably kept me going for most of this time. Do our bodies actually need sleep? Isn't regeneration and resting going on throughout the day? Do our minds need a rest, a time to simply exist and "cool off? " I don't know really, but I think that it is interesting to think about it. People seem to get irritated if they miss sleep, but what exactly does it do to us? If I just lay down and rest on the couch and read a book in the "sleeping hours," my body and muscles regain strength and rest that they needed, don't they? What is it about our minds that they need to be turned off from time to time? I wish I could just stay up my whole life.
