Once I was on a plane and a woman said to me, 'Now, what's the matter with my tomatoes?' And I said, 'Well, it's a bit difficult to see from here.' She took offence and said, 'I was only trying to be friendly.'

I wish we could grow up about it, I'm sure we are contributing to global warming, and we must do all we can to reduce that, but our climate has always changed. The Romans had vineyards in Yorkshire. We're all on this bandwagon of 'Ban the 4x4 in Fulham'. Why didn't we have global warming during the Industrial Revolution? In those days you couldn't have seen across the street for all the carbon emissions and the crap coming out of the chimneys.

I was very inventive. I lived in my own world - my dad said I was a loner. Not lonely, just happy in my own company. It's the same now. I need time alone, which is maybe why I love to write. Having said that, I love the sociability of telly. It's a nice contrast.

I don't spend much on clothes. I buy old books. I tell myself I ought to save - it's the classic Northern work ethic. I like good holidays, though. I'm a big fan of cruises. I love unpacking once and having the scenery change every day.

My wife and I always have a winter holiday that I call the "fly and flop". In January and February, you don't want culture, you just want to get your bones warm and eat, drink, sleep. We usually go to the Caribbean.

Georgian England, to see those wonderful houses being built. And the clothes were interesting too, although I wouldn't want to wear a wig. It's also the most beautiful period of English landscape gardening. They had famous gardeners like Capability Brown.

I think I was always realistic - well, not the Percy thing, that was ridiculous - but I never dreamed of being a racing car driver or anything.
