DNA scans can't accurately predict whether you'll be the next sports legend.  But according to some companies that are selling them, the scans can indicate the types of sports you'd be good at.

Is it possible that someone who isn't genetically geared to a sport could still be good at it?  Absolutely.  But whether or not these tests are accurate, they do bring up an interesting question:  How much athletic ability is genetic - and how much of it is the result of hard work?
