Newton’s Third Law – For every action, there is an equal and opposite reaction.
I punched a friend for fun in the shoulder and broke my hand five years ago (2012). He said I could but that was a big ass mistake. It hasn’t healed properly since. Now I have symptoms of carpal tunnel which is not good. If I play a game too much with my right hand, it starts to hurt.
So what happened exactly?
I threw a punch at this guys shoulder and my fist tilted as I landed the punch because he moved. Instantly I felt a surge of pain and I staggered backwards (karma). His shoulder had given back Newton’s Third Law, and I was screwed.
Lesson of the day, don’t mess around and punch your friends for fun.
