As far as McDojos and pre-teen "black belts" ... SOME TKD schools are notorious for this ... I've heard schools like this called "Take Your Do" and "Partial Arts". We also call them "candy shops"
It would save so much wasted time with defibrillators, sticking on the pads and analyzing rhythm.
Candy shops and take your do ... Lol - never heard of that one. Hilarious. I take it you practice some art/system? A mix of JKD concepts, XingYi and some Krav here. You? On the RyuKyu ...is that the George Dillman stuff? I’ve heard both positive and negative stuff about that. The positive is that it absolutely works. The negative is that in a real fight, with adrenalin flow and the shock of the attack, you will be limited to gross motor movements and not the finely tuned movements required to attack specific points that may be the size of an enlarged quarter. That in a real situation it may be quite hard to get some of the points taught. Which is why I like XingYi for instance - extremely simple and to the point, and the only pressure attacks are to points that are quite easy to get (eyes, throat, vagus nerve on the side of the neck, clavicle notch). What do you think?
Obviously you either are or were proponent of George Dilliman’s karate training. I used to go to Dillman seminars up to the point where he got all “mystical”. The last straw for me when he tried to convince me you could do a “no touch” knock out by throwing or emitting “chi”. When he started selling that at seminars and I then watched his “school-of-martial-training-and-thought” devolve into a quasi-religion complete with adoring disciples and with him as the prophet. Needless to say I quit paying any attention. It’s sad for me because I really enjoyed his seminars and he did put on a road of completely redefining my understanding of my past training. I give him kudos for that. Now he sells “magic” and I am not buying! That National Geopgrahic special where he made a fool of himself where he said the “throwing of Chi” didn’t work because the “chi tosser” did have his big toe raised or his tongue placed at the roof of his mouth. I was simply appalled for Sensei Dillman. But he did it to himself!
