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.

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.

At school I was called Fred, which is my middle name. At that time, Fred was considered to be a bit of a horrible name, so that's why. Otherwise, I was called Titchy because I was little. I was still only about 4ft something when I left school. I grew a foot under glass in my first year as a gardener. It's really quite amazing what sun and manure can do.

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 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.

Alan Bennett and Judi Dench are amazingly talented people who don't let you down when you meet them.

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.
