The BBC put together an online tool that tells you what Olympic athlete is your closest body match. It's just based on height and weight but it'll make you feel good (unless you're a dude that has the same body specs as say a female Romanian gymnast). Good luck.

Apparently James Tindall (a Hockey player from Great Britain) is my closest body match in this year's Olympic games...not sure how I feel about that, is that Field Hockey?. Find your match HERE.
