I have a BB in Aikido, I highly recommend some form of self defense for everybody.
Although I did wrist toss and hammer struck the wrong guy about 5 years ago... I went to jail and got sued.
And two weeks ago getting out of a club in San Francisco. Some jerk just got in my face and started mouthing off, I turned to my friend nick "A dude you see any cops?" I got the green light... And well you know what happened next. One strike, nite nite.
It's handy... and I'm not endorsing fighting at all.
Edit; Again I don't encourage fighting. I'm a really nice guy.
I worked very hard to get the rank I did. (paid in pain)
Been wanting to learn some BJJ for the last couple years. Did Aikido for 12.
