1. What type of Martial Arts do you take?
2. How long have you taken it?
3. How many times have you hurt yourself, and to what degree?

Personally I take Taekwondo, I've been taking it for 6 years, I've broken my wrist twice, finger once, arm once, ankle once, and dislocated my arm doing a backflip :D + a million other injuries like pulled muscles and all that good stuff.
