I don't like people being rude. Bad manners and arrogance make me cross. People making others feel uncomfortable. And I really don't like it in restaurants when people are rude or patronising to waiters. I feel like saying, 'They're not your slave'. But my knees only shake around once every five years. You're safe, don't worry.

I had the heaviest paper round in Ilkley, West Yorks, and if you look at my shoulders one is still lower than the other. I also did a milk round for a day. It was awful. I was a very surly milkman, because it was very cold, very dark and very early. I am a lark, not an owl, but not in winter when it's chilly. Apart from that I went straight into gardening at 15.

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.

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.

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.

You hope people won't be tricky or miserable. If you're in public life, it's important not to be. If someone says, 'I like your programme, thank you,' you should be grateful. I am. Why be nasty?

Julia Roberts was really rather lovely. I had to interview her on Pebble Mill At One years ago. You learn not to be starstruck if you're trying to get a decent interview out of someone. If you fall apart it's counter productive.
