Related but at a tangent - after a lifetime of interest in karate I came to realise that most of the stuff taught at karate is not practical. Katas and karate punches and kicks - most of this better thought of more as dancing or ceremonial. A bit like Tai Chi - except that Tai Chi claims no real world martial value. The myth remains however of karate being great self defence training. Our local karate club is packed…
I studied it for a few years as a kid, and came to a similar conclusion but had assumed it was that particular flavour of karate being an overly formalised, functionally ceremonious, branch emphasising discipline, flexibility and strength over fighting prowess.
A foundation, rather than an end-product if you will.
