My entry into the environmental arena was through the issue that so dramatically - and destructively - demonstrates the link between science and social action: nuclear weapons.

I'm not a fighter but I would love to be a boxer because I love the courage and toughness. I mean there can be nothing more terrifying than walking into an arena and looking at Mike Tyson in the ring.

You get to bring your own sound system when you play an arena all the lights and visual stuff which I think is really cool. There's something about those old arenas where it feels larger than life.

I did the best I could and in some arenas my best was not good enough. I've made some bad choices.
