Parkour.

Parkour is this thing from France that you have to be out of your mind to attempt. These guys find ways to leap, fall, climb, and jump over shit like you wouldnt even believe. Then they are gone before you knew some 150lb french dude just flew past you at full speed twenty feet above your head;and youre like "but wait where'd he go?"
This is the type of thing that requires you master understanding of both the mechanics of your body and the mechanics of your surroundings. Science Patrol salutes Parkour for giving physics the big "vas te faire encule". That said i present you with this video, showcasing some real life parkour in action.
