Taekwondo. Lacks mystical energy crap, and is practical.
I don't know. It's always seemed more about point scoring. When we practiced against advanced students, they relied too much on kicks which aren't very practical against anyone who knows to move in. The sparring is too controlled. Plus, in real life you aren't wearing padding. That's just my take. But then I think some of the mystical "crap" has a physiological basis. How many of us breathe deeply?
Modern Taekwondo is a sport and it can be great fun. If you can find a good school that isn't just a belt factory, it's well worth doing. Particularly if they teach a little Hapkido on the side.
