Oh and I have no illusions that I can go toe to toe with a guy in good shape trained in MMA in his 20'3 or 30's. I know that I most likely will get my ass kicked
This is why you never go "toe to toe" with anyone. The older I get the more I am willing to employ lethal tactics first and quickly.
I would never enter a fight with the idea of being tough enough to out last any opponent.
