20 Athletes That Died Before Their Career Was Over

I read the headline, "20 Athletes That Died Before Their Career Was Over" and thought that here were some truly spectacular sports players.  It takes a lot of physical fitness and stamina to continue playing a sport at a professional level after death.  That, or whatever illegal drug they're taking to boost their performance?  I want that.

Turns out when I clicked over to the actual story, that it was really more like a "20 athletes that died before they were over 45 and tore up every ligament in their bodies" sort of story.  Which, meh, is not as exciting.
