A guy I grew up with has been churning world class kid fighters for years now. He personally made it only on a national level, at great cost to his body. Karate is no joke. As a side note, having watched all 3 seasons of Kobra Kai, I find it amazing that in all 3 seasons they only managed to pronounce the word "karate" less than 5 times. Making a movie/TV show about something you cannot even say right "Kawatee"...
