I don't read good books anymore, it seems; I just buy them and put them on the shelf and every now and then walk over and pet them. I'm like the optimistic dieter who fills her closet with clothes two sizes too small and dreams of the day she can wear them. I know just what I want to do when I retire.

When someone tells me, 'Oh, we have so many problems on Earth; space exploration costs too much money,' I say, 'I absolutely agree with you. But I still hope we do it.'

I don't fear death so much as I fear its prologues: loneliness, decrepitude, pain, debilitation, depression, senility. After a few years of those, I imagine death presents like a holiday at the beach.

I don't write on topics that require a lot of urgency. But in 'Stiff,' I wanted to change people's hearts about organ donation. Whenever I get a chance, I try to talk about that.

To keep your he-man jaw muscles from smashing your precious teeth, the only set you have, the body evolved an automated braking system faster and more sophisticated than anything on a Lexus.

I used to do my best thinking while staring out airplane windows. The seat-back video system put a stop to that. Now I sit and watch old' Friends' and 'Everybody Loves Raymond' episodes. Walking is good, but here again, technology has interfered. I like to listen to iTunes while I walk home. I guess I don't think anymore.

Pet foods come in a variety of flavors because that's what humans like, and we assume our pets like what we like. We're wrong.

Picking my topics is sort of a process of elimination for me. Most things don't work for me. I like to cover science and unexpected things happening in labs. Also, theoretical research doesn't work for my style. I need scenes and interactions. Then, humor. I'm having the most fun when I can have fun with my work.

My books are not really books; they're endless chains of distraction shoved inside a cover. Many of them begin at the search box of Pub Med, an Internet database of medical journal articles.
