Martial Arts. Who has practiced/practices them?

[Hitman]

Many years ago I was a devoted fan and practicer of amateur boxing (Helmet and big gloves; my big nose would not hold up anything else) but now two litte kids, a real life job, and the SH series have killed any chance of having time again for that. And I miss it....really. So I'm curious to know who of you have practiced/practice any form of martial arts and which one do you like best. I'm not asking the typichal "who beats who" question; it is very clear to me that boxing is more a sport than a martial art and there are many fighting techniques that are much better for survivor and self-defence, but I'm interested in knowing how many people here have that gut-desire I have always felt to put the body, reflexes and mind to a test in the ultimate challenge: The one that gives the looser a good kick or hit in the face:p Those of you who have that feeling inside...that irresistible pleasure in teaching your body to become a fighting machine and challenge another guy will know what I'm talking about. Those are the ones I expect to reply and tell me their experience
