Skateboarding Superstar Tony Hawk
At age 41, Hawk is retired from the pro circuit, but still skates in a traveling show. On the subject of retiring, he says, "I don't put any ultimatums on it. I imagine if I was 50 that might sound ridiculous, but at the same time, I never thought I'd be doing this at 40 and here I am, at a top level, and I love it. As long as I feel like I've got my skills in check and I walk the walk, I'm doing it on this level."
