Any type of Martial and or Combative arts?
If so, how long, and would you say it changed your look on life?
I have been in Kyokushin Karate for about 9 years and it made a dramatic difference. It's awesome when you can walk down the street and not worry about getting hurt.
Oh, and being able to say for the most part, "look at that thug, I can whip his ass," is fun to say haha.

I also involved myself with Krav maga but, Idk, didn't really click. And I am studying the philosophy of Jeet Kun Do.

How about you guys?
