I tried the paleo diet, which is the caveman diet - lots of meat. And I tried the calorie restriction diet: The idea is that if you eat very, very little - if you're on the verge of starvation, you will live a very long time, whether or not you want to, of course.
I had very strong feelings, so the chance to make a film that deals in an imaginative way with stuff you care tremendously about is a real high. It's a really amazing thing to be able to do.
