The simmering sprinting feud between the United States and Jamaica will be reignited at the Bird's Nest this weekend, but you'd never know it by looking at perhaps the calmest man on the planet, Usain Bolt.

The world record holder in both sprint events casually lounged in a chair in front of a select media audience at the new Nuo hotel in Lido on Thursday, answering questions ranging from his rivalry with US star Justin Gatlin to if he will suit up for his favorite soccer team, Manchester United, after he hangs up his spikes.

He was even asked to name his favorite love song on Chinese Valentine's Day.
