I may have mentioned it in the past, but I am into Martial Arts, I practice a form of karate called Chito-Ryu. It is a really deep Martial Art that attempts to demonstrate the art aspect over the sport style we see in North America.
As you learn you are taught why certain moves are used, how to defend yourself and how to practice effectively. Having said that, if I was ever forced to use this to defend myself I hope I can find and wear some Chuck Norris Action Jeans so I can round house kick even while being stylish! My sensai is going to kill me!
