who is the most fattest person to ever live
by Chuck Klosterman on July 16, 2011. Allow me to spare you the hyperbole: Usain Bolt is fast. He is, as far as we can tell, the fastest human whoâs ever lived â in 2009, at a race in Berlin, he ran the 100-meter dash is 9.58 seconds. This translates to an average speed of just over 23 mph (with a top speed closer to 30 mph).
