The number of hours in the past I spent in "martial arts training" is thousands of hours. Many. In full contact sparring more times than I can recall. The number of RL "fights" I was in - if that is what they are called - also many - lots. Mostly as an adult that was part of my job. Noting this was in the growingly distant past, back then I was about the last person on earth any other man (or men) should try to prick around or mess with. I hurt a lot of men in my past. Never a bully - I broke bullies - and never looking for a fight, nor motivated by anger or pleasure. Just doing what needed to be done.
However, I never entered ANY competitions of any kind and don't have so much as a white belt. The lawyers were adamant that I NEVER obtain any ratings of any kind. Nor should I ever carry or use a weapon, even a weapon I took from the other person - and I went out of my way not to cause any permanently crippling physical damage to the other man/men.
This case is exactly the reason why. Back then I looked tough and mean as hell, and I was tougher than I looked - a lot. If added to that was boxes of fighting trophies and top ratings in multi-forms of martial arts would have changed it from "just being a fight" to a pro breaking up a seemingly defenseless person. By listening to those lawyers and doing (and saying/not saying) EXACTLY as they instructed, I don't have so much as a parking ticket conviction - though I was questioned, brought and even detained for a while by police on dozens of occasions.
(Having canned "witnesses" in my pocket also helped, but that's another matter. :lol
