I heard about this site on the radio today, and thought it sounded pretty intriguing.
I haven't taken the test yet, myself (it apparently takes about half an hour), but I liked the way the guy was talking on the radio today.
One of my favorite points he made is that really being healthy isn't about being a "super" athlete or anything extreme like that. He quoted Governor Arnold as once having said something to the effect of, "There isn't an athlete I know who hasn't destroyed their body for their sport."
If anybody does try it before I do, let me know what you think.
