I wear my lines like a soldier wears his medals. They've been earned. They've been fought for - so there's no reason to be ashamed of them. In your 50s, you just care less about that sort of thing. I think it's to do with what's inside you. You can't obsess about the outside.

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

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 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.

Whether it's a good thing or a bad thing, the higher your profile, the more castable you are in TV dramas.

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.
