It is true the biggest trash talkers are the last to fight. Fortunately I'm getting past that age, but I've always have had the attitude that if you insist on fighting you better know your stuff, because even if you can ultimately beat me, I'm going to do hurt you as bad and quick as possible whatever way I can to incapacitate you. Fighting to me is like guns, don't start it up if you aren't ready to use stopping force.
On that note, about 10 years ago I was part of a discussion with some younger guys who said they like to fight and all that. I told them point blank that me and most older guys would just as soon kill them than fight them. Very stunned looks on their faces, guess it just got real for them. But it's true, I have zero time for that crap and even less patience.
