That's pretty much the theory of the purpose of sleep that I've long found the most convincing, from my own experience. So it's nice to have some experimental corroboration.-I saw another article recently about IBM using an "artificial blood" system to cool a computer, by analogy with the way the brain operates. I think it said the human brain only works on 20 watts!

But it is said the brain takes 1/4-1/5 of all our caloric output per day.
