Its sheer delight to see sports persons doing best in their own sporting event.
It's use of power without harming others.
It gives pleasure.
I personally enjoy athletic events, next is wrestling and weight lifting.
Usain Bolt sprinter of Jamaica has given a great performance setting world record in both 100 meters sprint and 200 meters sprint.
He won the 2008 Beijing Olympics 100 meters sprint gold medal in a world record 9.69 seconds, gesturing to the crowd and slapping his chest before crossing the line.
He won the Olympic 200 meters sprint in 19.30 seconds.
It's sheer pleasure to watch him win.
