Bolt was absolutely insane in the 100m, I still cannot believe it. And its not like he is incredibly muscly or built either, he is just a freak. I suppose he is pretty tall though.
Also, I understand where you're coming from MissAshley with the Chinese girls, some of them looked like they were around 11 or 12 years old. They were still pretty amazing though, I could never do any of the things those gymnasts do.
