One of the perks about where I live, there are several schools. Technically I'm in Karate, but both senseis are black belts in many styles and we get to learn techniques from hapkido, aikido, ju juitsu, judo, capoiera, and taekwondo. I like judo the best myself, cause you really get to use all your strength, all the time.
Any martial arts are fascinating studies. The bulk of our students are kids age 4-11, the next biggest group is teens, and there are four of us in our fourties, quite a spread! And gals outnumber the guys probably 2 to 1.
So its definately not a bunch of Chuck Norris wannabe's, at least where I live.
I like the movies and shows like Human Weapon (which I haven't seen, thanks for posting this, I'll check it out), but there is a lot more to it than the physical stuff. I train learning that the best self defense is not to be there. I also hope I never have to use it. In the meantime, I have fun with it and get a great workout, both mentally and physically.
