It doesn't seem like you'd have to be as rich as Bill Gates to at least be a pseudo Batman. And a lot of rich people are psycho. Just look at the things they spend money on.

I think about it a lot, but it struck me the other day again when I was watching some weird thing about some skier. His goal in life is to achieve this life threatening skiing feat. Sometimes I just wonder if you have the athletic skills and the money for hobbies like that, plus the complete psycho daredevilness, why don't you do something useful, huh? (Of course, it costs more to be Batman than to ski, but that's just an example of something that makes me think about it.)
