Basically, the person in the White House should be principled, should have a philosophy about food that relates directly to organic agriculture. I will continue to push for that.

If I weren't involved with food, I'd be working in architecture. Design is that critical to me.

I feel like old age in America is a very sad thing. I have been many different places around the world where getting older is something you look forward to.

I really appreciate the many neighbourhoods of Berkeley. There is still the butcher, the baker and the candlestick maker. And it has the University of California, which is the greatest gift, to my mind, to be close to it. It keeps the place alive.
