This of course is old news but I feel obligated to talk about Usain Bolt and his 9.58 100 meter. The man is very talented! I honestly would not think he would be that fast just from watching him run, because his stride frequency seems much slower than someone like Tyson Gay. Usain is tall so he has long strides, to be that fast on top of being that tall is unique. The fact that Usain is young is very unique too, he has broken the world record early in his career, imagine what he will do as he gets older. He doesnt have the fastest reaction time for the start, but his raw speed makes up for it. We all shall see what he is capable of and what new abilities he can put on the human race.
