Years ago, retired. I now practice some katas on my own, light weights, light stretching. Did some aikido, jiu-jitsu, street fighting style, Tae kwon do (Jidokan), shotokan, shorin-ryu and I am leaving out one or two and some knife fighting. Probably helped more then hurt. Paying now with some old injuries, have to have a shoulder cleaned out (May have been from football). They combine the stuff now, you get to see what actually works, MMA, UFC etc.. I will take my hand gun training over any of it. Damn good hobby, learn but try not to get too banged up. Better to walk away and avoid shit.
