I think being raised by a single mother put me on the outside, and I would watch my mothers married friends and think, Why does she put him down in public? or, Why is he so rude to her? It seemed to me that there were very few marriages where the couple were genuinely in a supportive, loving partnership.

I've been a single parent for a long time. It reminds me of being a waitress. As you walk back to the kitchen, requests come at you from all sides. You're doing the job of two - you have to be highly organised.

I try to live my life as honestly as I can, and the last thing I want is to pretend to be something I'm not. To pretend to myself I am a sex symbol would somehow be dishonest. I'd feel, in my heart, that I were behaving artificially and that's the last thing I want to do.

I am simply not such a slave to my vanity, and I don't want to be, because as you get older you really have to start accepting the inevitable.

Im mad keen on recycling because Im worried about the next generation and where all this waste were producing is going. It has to stop. I wash out my plastic containers and recycle envelopes, everything I possibly can.

I've always been terrified about not having money. I've been a big saver and a big earner. When I've been out of work, I've always found another job. I never wanted to get into debt, because money was very tight when I was growing up. I never felt deprived, but I couldn't have the things I wanted.

I really enjoyed staying at an encampment at the top of a hill in the Samburu Reserve in Kenya. You reach it on a small plane; there is no electricity, no city noises and you sleep and shower under the Milky Way, with moths fluttering around a kerosene lamp, knowing that there are elephants and lions roaming free in the valley.
