I switch off lights like a maniac. I drive at reasonable speeds so that I don't waste petrol.

In petrol stations on the motorways where people have left the place looking messy, I clear up each lavatory I happen to have occupied. When people drop paper on the ground, and everything like that, I pick it up, put it in the lavatory, and make that room look nice.

I've been dealing with the press for 45 years. You need a very long spoon to sup with them. While you are always grateful, they are like badly trained dogs. They smile and wag and bite your arm off.

I love a cardboard coffin. Both Mummy and Daddy went off in cardboard coffins, painted - Daddy's was rifle green. Beautifully made.

Even clingfilm - if it's gone over a salad bowl, take it off, use it again. I wash out carrier bags; I save brown paper from parcels. I save string; I save ribbons. I separate all my bits and pieces.

In Kenya you've got the great birds and monkeys leaping through the trees overhead. It's a chance to remember what the world is really like.
