The video is just a fun tongue-in-cheek look at Johnny's perspective that surfaces some random stuff Daniel got away with ...
But that article is spitting some legit truth.
I remember growing up with some kids who took Tae Kwon Do since it was the local martial arts place.
That place wasn't anything more than a glorified daycare. All they did was take parents cash to watch them after school, give the kids belts as they grew up, and all the kids did was memorize borderline choreography and break boards. They sparred like 1% of the time. There was no focus on the mental aspect and wasn't no focus on transforming the body physically through hardwork at all.
