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've covered a lot of the British countryside and the UK from top to bottom and side to side. It's such a pity more people don't appreciate what's on their doorstep.

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 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.

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 never get bored of my wife. It's lovely.

When I'm in Italy on a Friday night, my first supper there is a big bowl of fresh pasta and a glass of local wine, sitting outside. There's nothing better.
