Usain Bolt Sets A World Record For A 100 Meter Indoor Race

Damn I love watching these guys run. I love the Summer Olympics. If I was forced to choose on event and no others to watch live, it would be the Men's 100 Meter final. In any race it's exciting, especially when phenom Usain Bolt is running. Now watch him break the indoor world record. Can a new outdoor record be far behind? You all do realize that there is only SO fast that a human being can run. If you factor in muscle mass and height and weight and a thousand other factors, an upper limit of human speed can be mathematically arrived at. I wonder how fast the upper limit of speed is.
