Have any of you read the new article in JAMA about a karate style known as Koshin-Ryu?

Any one study the system?

The system looked very connected to it's chinese origins and I believe I read that it might of been one of the original ninjitsu ryus that came over from China.

Looked like good stuff and it was a very interesting article and a bit refershing from the gloss covered crap in black belt that I have been reading of late.
