Usain Bolt

Jamaican Olympic sprinter

Age: 27

The 6'5" sprinter has broken three world records and has six Olympic gold medals under his belt — and he's only 27. Though known for his speed, he's been slated with saying that he may try different events at the next Olympics, but plans to retire afterward.

The most recent reports claim Bolt had dated a British office worker until December 2012; as far as we know, he's still on the market.
