In 2002 Ethan Zohn spent 39 days on the savanna to win reality television show "Survivor: Africa" -- and its million-dollar purse. Long before he was the last one standing, however, Zohn played Pop Warner football. From the fifth through seventh grades he was a running back and defensive back, but still wonders if he should have stuck to playing offense. In year three, he made a tackle that broke his collarbone. Despite his injury, he finished the game before heading to the hospital. That dedication came in handy as an adult, when Zohn played professional soccer, then successfully battled hunger and herds of hoofed animals while being filmed for reality TV. Today, he runs Grassroot Soccer, a non-profit organization he founded to train well-known soccer players to educate at-risk African youth about HIV and AIDS.
