You cannot hide from the world. It will find you. It always does. And now it has found me. My split second of immortality is over. All that's left now is the end, which is all any of us ever has.

I've hated cockroaches my entire life.Tweeting jokes about it helps me cope, in a way. I'm not as jumpy killing cave crickets as I used to be. I still jump plenty though.

The idea for me came when I was watching a 60 Minutes segment about resveratrol, the chemical in red wine that lets you live longer, supposedly. And they were like, "Who knows, maybe one day it will help to cure aging." And I thought, "Well, if they did that, we'd all kill each other." And then I laughed, and then I thought about how precisely that would happen. That's how the book came to be.

I took time in the day to write as much of the book as I possibly could. I didn't write too much at night, because I don't like to - I'd rather watch TV.

I'm always amazed by people like David Simon or the people at The Simpsons or J.K. Rowling who can create dozens and dozens of memorable characters. It seems so effortless, and even people who have just three lines in the shows or in the book have a very distinct personality, and you can feel the richness of their personal history.

I found that life for me gets a lot more serious as you get older. You start off young and happy and smiling and "Wooo! I'm having fun!" And then you get married, and that's very serious, and you have kids, and that's very, very serious. So as you get older, you start thinking about passing away, and that becomes extremely serious.

I think it's the next thing, getting out of the comfort-zone readership, that at some point you have to try and break out of that and see if you can go in new directions. I wanted to do something that felt a lot bigger than a book that's going to sit on a toilet.
