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?

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 love Paris for its wide boulevards and cafes, and Rome for the ancient history, as seen at the Forum.

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.'

It's never much fun at school - it's just dates. Then as you get older, for some reason, you get more interested.

People think cruises are for old folk, but they are amazing, as you get to see so many places, and you're never stuck as you're docked in a different port every day.
