This is kind of like that Sports Science segment ESPN does, except that its cool as f*ck, and the narrator doesn't digress into tagents about bodily processes nobody really cares about.
All that aside, this is a really cool take on how much faster humans (and their shoes) are becoming. Will Bolt's supreme speed last for generations to come? As amazing as the man is, history shows its pretty unlikely.
