My point is this. There are many things in life you just won't be able to understand no matter how hard you try. One example might be your girlfriend. Another - simple math. Yet another - these sweet interviews, the-greatest-of-all-time, Rickson Gracie, did a few months ago to promoting the release of his book in Japan. Yes, it's one thing to do an interview in Portuguese that is subtitled it in English (helpful). It's another thing when that interview is subtitled in Japanese (less helpful).
But, it's Rickson, so just watch and try to absorb all the Budo and Jiu Jitsu magic you can. Just keep trying. Repeatedly.
