To you, what is the grand unified theory of jujitsu? You know, if you had to put the summary for jujitsu on the back of the box and explain to people what is it, how do you do it, what is it to you? What is the one theory that encapsulates everything else that we do on the space and the mats?
7:21
Yeah, I'd love to explain.
7:22
Yeah, I mean, I think in terms of books, I mean, there are plenty of jujitsu books, and a lot of them are really successful.
7:28
But this might be the first traditionally published book, as in like a book that you could buy in a bookstore, which is purely about jujitsu concepts, right? So it's not just a list of techniques.
7:38
Not that those books aren't great.
7:40
Like, I really do love reference books with photos of techniques in them, and I do have some photos in the book as well.
7:45
But in terms of a book that you can just crack open and read and just talks almost completely about how jujitsu works at a low level, I think this might be the first time.
