Cool stuff....I know a guy here in town that fights UFC and he doesn't look that tough but he is.
I have seen him come into work whrn I was at HP and he looked like hell, but he always said...you should see the other guy...lol
Back in the day, I might have tried it, I was into martial arts and had a chip on my shoulder, now I would just fall over in a corner and cry for mommy...lol
