Some interesting Martial Art related articles I came across:

Most martial art styles employ joint locks and pressure point attacks in their fighting arsenal. In fact, as a rule, the more joint locks and pressure point attacks a specific style utilizes, the more advanced that fighting style is considered to be. In Chinese martial arts there is a name for this method of attack. It is called Chin Na, and is translated as the art of seizing and applying joint locks.

(Remember Crouching Tiger, Hidden Dragon? Yep – this is it.)
