The fastest man

Now there is a new fastest man and that is Jamaica's Usain Bolt as he thrills with 9.69sec world record. If you have seen that match, you can see how he open up his strides and his legs were so long that he easily became the first guy in the front ahead of the rest of the runners. Towards the end knowing that he will win the race, he let his hands off calling for some sort of celebration. Could he have actually run even faster if he continues to run with his hands movement like in the start when he run? But no matter what he is now the world's fastest man.
