If an old man willingly gets in the ring with you, bow out of the fight immediately. Save yourself the concussion.

Ouch!

When I was in my late 30's one of local elderly men ask me to do a favor for a fellow I had a run in with a week before.
When I refused he got red in the face & challenged me to a fist fight.
Now this old man was probably 35 years older than me.
I started laughing which really pissed him off.
Then I explained that there was no way I could win.
If I beat him up, that would not be good & if he beat me up I would never be able to live it down.

Also never fight with a little man;he'll kill you.Years ago I worked for a carpenter that was a con man once upon a time. I offered him a bet that I could flip a quarter into the air with one hand + with the other pull my buck folding hunter,open it one handed + strike the quarter before it hit the ground. Of course I could do it,I did it every day as practice. He would not bite. He said these words of wisdom,"Never play another man's game at his suggestion."
