No I don't wonder about that. I told you that this is my concept. This is something I use and teach students. I actually take pride and joy that nobody else "to my knowledge" uses this concept. That just means that I may know something that someone else doesn't know.well i try not to just state the obvious, but do you think their may be a reason why nobody else in the world does it ?
I could easily explain "Shield and Spear" and someone may say.. "Oh that's similar to what we do, but we call it...(insert name)" That's a possibility. But if not. Then I'm happy to be the only one that knows it, besides the students I taught.
