TV shows and movies too. I like NCIS, but these pretty little girls who weigh 105 lbs and have arms like pipe cleaners taking down husky men by poking their tiny hands at just the right places is absolutely delusional.
Good points about TV fighters. Unrealistic.
Only thing that might be supportive is I met a master of Shorin Ryu martial arts at my dojo on his tour of the US in the 1970s. He was really small but in competitions and demonstrations in his life he defeated the biggest bad guys.
But I believe most times it’s like the Woody Allen line:
“To me, in martial arts the bigger your opponent the bigger the beating he’s about to give you.”
