The best things said come last. People will talk for hours saying nothing much and then linger at the door with words that come with a rush from the heart.

In 2003, I almost died of an intestinal blockage when I was on a mountain in Chile, filming a segment for 'Scientific American Frontiers.'

As I am becoming older, the only thing that speeds up is time.

I've never tried to manipulate my image.

The one hour live debate in the West Wing that we did was one of the most exciting times for me on stage or on camera, because anything could go wrong.

I used to be a Catholic. I left because I object to conversion by concussion. If you don't agree with what they teach, you get clobbered over the head until you do. All that does is change the shape of the head.

The difference between listening and pretending to listen, I discovered, is enormous. One is fluid, the other is rigid. One is alive, the other is stuffed. Eventually, I found a radical way of thinking about listening. Real listening is a willingness to let the other person change you. When I’m willing to let them change me, something happens between us that’s more interesting than a pair of dueling monologues.
