Insomniac Species??

Im remembering back in my psychology the discussion we had about sleep. No one REALLY knows what sleep does for us. Yes it relaxes us, helps us heal from sickness and wounds. But there are many theory's about what it does. Some even say that it helps us remember stuff.
We all know that sleep helps us get better.

But have you ever thought about why?
I think its cause our brain uses so much energy and resources that the rest of the body only gets minimal amounts. Just enough to function properly and sometimes when needed a little more for short periods of time.
Then when we sleep the brain pretty much shuts down. So we cool off and the body gets more resources to fix itself up. You could think of it like a computer. When you put it in sleep mode, you cant really use it, it just sits there holding the desk down till its needed again. But it also uses less electricity and cools of a lot. Now obviously the computer doesn't heal itself, because if you shut it down cause it was being FUBAR then it will be just as FUBAR as before if not worse. That's just most of the time, but anyways.

I don't know about the whole memory thing, but I do know that stress can make one forget things and sleep slightly relieves stress. But then maybe thats just me. Ive also heard that you age slower when you sleep. But that sounds kinda wild.

One thing I notice is that although I do seriously enjoy sleep. If my body did not require it, I wouldnt do it. I mean if I didnt have to, if it was a choice, I wouldnt. At least not as much. I could get so much more done if I didnt have to sleep. During the day I could work on my car. At night when theres no light. Id get school work done, play my videogames. That would make for a much more productive world. Again Im not talking about our human race as it is doing this. Because that would make for a very grumpy species. I dont know what the statistics are, but I know we spend alot of time sleeping. If we didnt Im willing to bet that we would be a much more advanced race.
