Why do I do what I do?

This thread is just a brief reason why I do triathlons. Seeing that many people turn their lives around is just wonderful to see. It's just amazing some of the before and after pics. I'm sort of jealous because I can't ever say that I've lost 100 pounds. My the lowest I've ever been since I started college was 168 and the highest was about 202 so that's only a 34 pound range. Ok, enough of me. These people are truly inspiring.
