> See this is why I get annoyed at a body evolved for caloric scarcity. We shouldn't get tired, we should get hungry! Oh, pollutants build up in the brain? Burn more energy to get rid of them! I should be able to strap an icepack to my head

Well, you did identify the major problem with the unlimited overclocking plan. Burning more energy generates more heat. An icepack on the side of your head doesn't solve the problem; at some point your brain (and the rest of the inside of your head) will cook, which is fatal.
