Actually, I've been training (As examples Aikido, Fu jow, Ken-jutsu, Bo-jutsu, Ying Jow Pai, and a little Wing Chun. I've only come to instructing level for Aikido and Fu-jow due to me failing a master belt test.. but yeah.) for over ten years now. Religiously. And I'm used to NYC "ghetto" trash picking fights. I kinda froze when he threw the punch. Which isn't normal, since it was a sloppy and crude over the shoulder punch he threw. Dunno what that was about. He's family, but I do not like him. Besides that, jujitsu is an overly populated system unless you're referring to Brazilian jutsu.
And even then, it relies on using your weight against someone too much for it to be really effective to joint lock someone who knows what they are doing. It's also useless against large groups of people when the focus is to entrap. Although, it does complement Aikido well due to the very--very awkward throws that it offers as well as joint-take downs.
Regardless. I just choked this once and payed for it. Although, I'd imagine the shoulder dislocation is not doing him any justice. My wife suggest it's a family thing.
*Takes this stuff seriously. >_>*
Otherwise, I'm thinking to not go since it's one of my front teeth and they are strong normally.
