We love the videos of Dusty Smith known as CultOfDusty on Youtube. He is a person with bone in his nose mixed with opinion about most issues. His language is free and he serve us everything cold, direct and unprosessed. Enjoy him!

I read somewhere (it was a Tai Chi book by a well-respected practitioner) that it is a kind of non-written agreement between both persons, that is, I apply you the technique, and you will fall-pass out-bounce… so allthis is a kind of game, and not a real martial art.
