Naturally you did. That's why you CAN write and write a cohesive sentence. Head-as-punching-bag bodes poorly for ANY man poor, stupid or desperate enough to box for a living.
I was lucky enough to be bad at boxing, bad enough at it that making a living at it was never a choice.
I did use what I learned in that class once. As a LT in the Army a large soldier with a loud mouth suggested that someone should whip the LT’s but. I had the 1st Sgt march the company to the gym, and called a friend in to referee. The soldier smoked, and big slow guys who smoke, well they don’t last long.
After 2 rounds he couldn’t raise his arms. We had no more of that.
