Largely this is a class thing - writers tend to be cosseted little middle-class kiddies who think that the world owes them a royalty cheque. But just doing it - being in your room for years on end, locked in your head, alone with invented ghosts - it weakens and softens the body. And I know I can't just live in my head.

The thing I care about is my weight - I'm as fanatical about it as a member of Girls Aloud. I weigh myself every morning. I know exactly what I want to be - 82kg - and I try to stick to it.

The thing to remember about Phuket is it's very beach-oriented and relaxed. The trendiest beach is Koh Sirey, which is full of groovy places to have a cocktail and watch the sun go down.

There are a handful of barbecue seafood shacks on the beach at Hat Nai Yang, which is a fabulous place to have dinner. It's very much run for locals and they serve the catch of the day, which might be lobster, white snapper or squid. It's ridiculously reasonable, too.

I don't think much of anything I wrote before the age of 30.

I think airports are places of huge human drama. The more I see of it, the more I am convinced that Heathrow is a secret city, with its own history, folklore and mythology. But what has surprised me is the love the people who work there feel for the place. Everyone seems to think they are plugged into something majestic.
