In '73 I photographed the cannibals in New Guinea. They treated me OK but they didn't make you feel relaxed... I managed to escape unscathed though, I'm pretty good at that.
Playing a show before thousands of people is a highly unnatural state and when I get on the mat to do an hour of yoga before the show, I come out physically relaxed.
The more relaxed you are, the better you are at everything: the better you are with your loved ones, the better you are with your enemies, the better you are at your job, the better you are with yourself.
Something I'm going to try to really instill in my own family is a lot of tradition. And, I used to have a lot of superstitions, and then I realized that it was kind of hogwash. Once I let go of them, I relaxed a lot.
