''Can'' being the operative word.

Its the probabilities involved which many are having a hard time comprehending.

I'm familiar with bjj. My posts refer to time investment vs expected results/intention of the class.

If a woman is going to invest only a small amount of time, these classes are next to pointless. A better investment of that brief time would be a little academic research of small point attacks, male psychology and criminology.

If the class is tailored to one motion eye/ear/throat attacks and grip escapes then it may be worth the investment of time.

If its lots of groundwork and throws for a few months that is a poor investment of time from the perspective of increasing survive-ability.
