Honestly I don't know how I got so wrapped up in all this nonsense. I can see it's fruitless now.
I apologize to Howard Chan.
Actually, having just read the rest of this thread, I agree. Your definition of internal is not the same as Mike's, I can promise you that. This stuff is more complicated and unusual than you think. I've trained with some of the best BJJ'ers on the planet, and they simply don't have it to any meaningful degree, and nobody would who doesn't pursue it deliberately. Someone like Rickson doesn't *need* it to be great obviously, which is important to underscore because no one is saying you can't be a great fighter/athlete/artist without it, but even the best don't get any of this just as some freebie that comes along with their other practice. You are, of course, as free to ignore that as anyone else is, and it probably won't impact your life much to do so.
