Usain Bolt

This dude is superhuman. As someone who has followed Track & Field sports his whole life, I can tell you that running a legitimate 9.58 in the 100 meter dash is mind-boggling. I remember when sprinters started to break the 10 second barrier with some regularity. I remember vividly the Carl Lewis and Ben Johnson rivalry for the title of world's fastest man, pushing both to do what, at the time, was considered the impossible feat of breaking the 9.9 second barrier in the 100 meter dash. But 9.58 seconds! That's just sick. Any faster and the dude will be flying!
