The BBC has a fun interactive widget online that matches you with an Olympic athlete according to body type. Just plug in your height and weight and it searches the athlete database for a match.
I did mine and was matched with Usain Bolt, which totally jazzed me, and British volleyballer Peter Bakare. Guess there aren't many other 6-foot-5, 205-pounders competing.
The feature can produce some curious results. A friend of mine -- a man in his 50s -- was somehow matched with ... a female Russian shotputter.
Check out the feature here and see which Olympian you are.
