I'm a proud Shotokan Karate-ka and Kendo-ka, what do you think I'll answer? Martial arts, of course. I've donbe a little boxing and kickboxing and I have to say that my Shotokan and Kendo require a far more exact discipline and study than do either boxing or Muay Thai. That was what really drew me to Shotokan and Kendo, this sense that it's a liftime thing, that I can devote myself to these arts and by the time I'm 77, I can still rip people apart if need be. I reall admire the (late) Sensei Iwamoto. Kept training until he was 86.
