I've got an overactive, analytical brain. I get frustrated, impatient, angry with myself. I swear at myself a lot.

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.

The advantage of age is that you swap youth for wisdom. You're so full of insecurities when you're young. 'Who am I? What do I have to do for people to like me?' You get caught up in things. You get very emotional about things.

I grew up in a very political household. My mum used to shout at the television. At Mrs. Thatcher.

War is good for absolutely nothing, because no matter how far and wide apart we may live, we're all the same under the skin. We all want to live, laugh and love.

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.

Sadly, the timing's never been right. There have been men who would have married me but I didn't feel the same, and vice versa.
