HumBio area of study: Air Conditioning?! I can still do the baboon alarm bark and the chimpanzee "excited, I've found food" calls from Jane Goodall's class - great party tricks and highly amusing to small children. I frequently quote Ehrlich's Rule Number One: "Don't Be Stupid."  Great program, my first preference is to this day a very wide-ranging set of viewpoints when looking at any particular problem.
