Ariel Hsing has had a great run at the Olympics as a member of the U.S. table tennis team. She was the only American to make it past the first round, she upset a former world champion in the second round, and she pushed the eventual gold medalist to the limit in the third round before losing in six tight games. And she’s friends with Warren Buffet and Bill Gates.

Did I mention she’s from the San Francisco Bay Area and is only 16?
