When you're 18, when you're at college, sports can be your life. You can watch every baseball game, every college basketball game, every football game. Once you have a family and kids, you can't do that anymore.

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.

You always worry and you always fear what's next. But you eventually just push forward knowing you can't really do much about getting rid of the anxiety. You see people get pets after their kids leave the house because they're so used to having something around to dote on and worry about.

You'll paint some nursery and the kid will want to sleep in a drawer.

On the Internet, Spencer Hall at Everyday Should Be Saturday is the best writer in the universe. He's very funny. They're jokes about college football, but they come from somebody who's clearly smarter than the rest of us; it's always fun to get your jokes from someone who's a genius.

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.

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.
