New Strategy?

So last night I was watching the Discovery Channel's series Planet Earth. (If you don't know what I'm talking about check it out at http://dsc.discovery.com/convergence/planet-earth/planet-earth.html ...so incredible.) The episode I decided to watch was called "Deserts." It seemed appropriate given our recent inhabitation of such a place. I learned that in order to keep cool in the heat of the day, kangaroos sit in the shade and lick their forearms. Apparently they have a large amount of blood vessels in that area and as the saliva evaporates they cool down. Now I know our vasculature is not the same as kangaroos, but when it gets too hot to handle down here you just might find me sitting in the shade, licking my forearms.
