My job happens to be sports-related, so it's like my duty to watch football. It's my job. But that's not a change for me. When you're 18, it's life and death, because you don't have a kid, and it's a much bigger deal when you're 18. Having a kid - when the Vikings lost the 2009 NFC title game, it sucked, and I'm not happy about it, but my kid is still alive. You have to have that horrible forced perspective that you don't want.

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.

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.

With toilet books, people don't review them that much. They don't really pay much attention to them. It's just like, "Oh, okay. I'll put this in your stocking."

You're going to have Yahoo! and places that don't have rights being much more aggressive in how sports news is covered.

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've always found that the best things I've ever written, or the things I like the most that I've written, are things where it's a pure idea, and you just follow it and put it down and see if it works.
