Our happy hour fact to amaze your drinking buddies with.

New research suggests people have the potential to run at speeds of up to 40 miles per hour.

Previously it was believed that elite sprinters, who apply almost 1,000 lbs. of force with each stride, are pushing up against the limits of how much pressure their muscles and joints can bear. Not true, as a group of scientists recently discovered while conducting a treadmill test. Apparently, other movements -- such as hopping on one leg -- actually apply even more pressure on one's body.

"Our simple projections indicate that muscle contractile speeds that would allow for maximal or near-maximal forces would permit running speeds of 35 to 40 mph and conceivably faster," explained one of the researchers.

Usain Bolt tops out at almost 28 mph. Many adjectives have been used to describe the world's fastest man, but we're going to pin him with a new one: slacker.
