Alzheimer's is a horrible thing. Some people are naive about it. They think, 'Oh it's just your memory,' but my mother was in terrible pain. Your body closes down. She didn't know if she'd eaten or if she wanted to eat. She couldn't remember how to walk. Towards the end, she didn't know us. It came gradually, then it got worse.

We stay in U2's hotel. They bought a hotel, The Clarence, a nice place and it's in an area where everything's happening, so many fantastic restaurants and bars and the people are so friendly.

When I was young, I used to wear a lot of wigs, and I was running on stage at a gig and tripped over and it fell off. It was in the 1970s, and Swansea were doing really well in the league, and most of the team were there. I almost died, but I picked it up, put it back on my head and carried on.

I remember when the Atkins diet arrived; I lost 16 lb in the first month, but when I stopped, it all went back on again.

I care a great deal about LGBT U.S. servicemen and women being able to serve openly and honestly. Since early in my career, I've included realistic LGBT characters in my books. The idea that a gay Navy SEAL had to hide who he was in order to serve was a terrible one - and I made sure my readers knew that!

If I had to think of what I would do different in my whole career, it's that I never would have picked up a beer, bottle of vodka. That definitely changed my life. That is an Achilles' heel for me.

To be captain and win a lot at Juventus, to play for 20 years, to play in the World Cup, European Cup, I think I had a good career, no?

You know, I never knew if I had any talent when I started in this business. My first job was being a page at The Tonight Show. I saw Jack Paar come out one night and sit on the edge of his desk and talk about what he'd done the night before. I thought, 'I can do that!' I used to do that on a street corner in the Bronx with all my buddies.
