I train for 'real world self defense'. Everyone I can talk to, every book I read, every forum I troll....err post at, each time I train it is because I want to be able to protect myself and my family from danger.
I don't go to bars or other places where I am likely to get into it with someone. Ok, I do take in the occaisonal metal concert and lurk on the rail....
I train full contact striking and grappling. I seek to avoid or escape 99% of the time. I train with pistols and rifles and sticks and boots. Single attacker, multiple attacker, you name it, I'd want to train for it.
I know a little, just enough to realize that there is so much more out there.
That's why I love Taekwondo. It's the bestus....
But seriously, why do you do what you do?
