Ju-Jitsu is fun, until your training partner plants a knee in your groin, then the fun ends, rather qiuckly!
Dude, she is a 5th degree black belt, she would choke you out in no time I like..
A knee in the groin is never fun ... And if one thinks so, everybody tells you, you're a pervert :-D
But the black belt doenst frighten me - Martial Art's are fun to watch, but if the one you fight against is way stronger than you, and the one you fight against doenst play by the rules of "that martial art", all the black belts in the world doenst help you - You'll just get you're as kicked then ;-)
