I get up to 400 letters a week, so I have a full-time PA, but I try to answer everything. People don't seem to realise that if they send something living in the post it's going to die on the way. Especially when you wrap it in a polythene bag.

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.

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 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.

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.

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.
