Over a year ago I changed my diet to a vegan diet, really just to experiment to see what it was like. And I felt better, so I continued with it. Now, for many people, that choice is connected to environmental ethics and health issues and all that stuff, but I just wanted to try it to see what it was like. In a visceral way, I felt better, so I've continued with it and I'm likely to continue it for the rest of my life.
