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.

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 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.

To keep my back from getting stiff, I have a strict regime every morning of stretching and do yoga once a week and Pilates. 'Strictly Come Dancing' in 2008 was great for my fitness.

I think it's nice to age gracefully. OK, you lose the youth, a certain stamina and dewy glow, but what you gain on the inside as a human being is wonderful: the wisdom, the acceptance and the peace of mind. It's a fair exchange.

I can honestly say I love getting older. Then again, I never put my glasses on before looking in the mirror.

I've never felt the need to be defined by a man.
