We grew up down the street from a master and sensei of Tae Kwan Do. He was a CHP officer. His son was my age, a friend, and a 3rd degree blackbelt. I never wanted to get in a fight with that guy. Narrowly avoided one at one point.
But then there was Phil, who also lived in the same neighborhood. We shared an apartment later in life and now he's my kids English teacher.
Phil was a CIF State Championship wrestler and he wasn't afraid of Ted (the blackbelt at all). Personally, in a real street fight, I'd pull the arm reach to the groin and keep squeezing! 😁
