Actually, I took martial arts training in the mid 90's. Excellent discipline and my exercise routine still incorporates several of the warm up exercises from the class. I'm way out of practice now, but can still handle my own if need be (against an untrained fighter, anyway). Just don't ever want to have to do that en femme!
On a side note, our master used to bring in street fighters for us to practice on during sparring night from time to time. We trained in a very tough neighborhood and these guys were very intimidating to go up against. We sparred full contact - there were not points, it was an all-out match (stopped by the master if need be). Amazing how easily defeated most of these street fighters were. Very sloppy fighters. Oh, it hurt when they landed a punch, don't get me wrong (got a lot of black eyes, and broken bones even), but they were never very good fighters. Good to know when fighting in real life circumstances.
