I can box, wrestle, karate, ect. I can also use a knife, tonfa (pr24), bow, chucks, sia, ect. I have knockout power in both hands despite only being 5'8" and 185. The problem is, there is always someone better trained or more willing to use violence. Plus I don't want to touch another person much less fight with them. In an emergency I can and will get nasty with the best of um. I'm also getting older, my muscles don't last as long, my joints crack and pop when I lift my leg to tie my shoe much less throw a roundhouse or sidekick. BTW hitting the head with those kicks is now only possible if the guy is the size of tattoo from fantasy island.
My best bet is to spot and avoid trouble.
