This guy is a machine. Even when he ran his World record time in the 100m he still was looking around a bit at the end.

I wonder just how fast he can run the 100m. And if he is just holding back a bit every race so that he can break the world record every time hes on a big stage.

His 9.58 record was in a race where everyone in race had run sub 10 secs and he still made it look easy.
