Are you healthy? I'm not obsessive about my health, but I certainly take it seriously.
Have you ever taken an antidepressant? No. I'm not a drug girl. My doctor prescribed me Valium once to help with the stress of going through a divorce, but they made me feel so horrendous I wanted to kill everyone.
Do you worry about your weight? Everyone diets when they're young, but I don't now. I'm not very much of a foodie; I like small amounts of delicious things but I've never overeaten - I'd much rather have a glass of wine. I'm lucky in that I don't like sweet things at all. My father loved cakes to such a degree that he kept forcing them down my throat when I was little and it put me off for life. He had terrible cholesterol, poor thing.
How do you feel about cosmetic surgery? We're supposed to be independent, liberated women; we fought incredibly hard so that we can work and make money and we can go and have bigger tits if we want, and yet it's us women that judge those choices. I think it's a bit late for me, personally.
How much sleep do you need? Seven to eight hours. I'm getting about six at the moment; it's extraordinary how it shows at my age.
Is sex important to you? Oh, absolutely. I think it should be to everybody, unless you've made a decision to take a vow of celibacy. It's vital.
What's your attitude to smoking? I smoked all through the 70s, on and off, but to me it's like having a piece of chewing gum, it's absolutely not addictive. In this job, I have to smoke four or five cigarettes a day, and when I've done that before I've managed to stop with no trouble whatsoever.
And drugs? I'm not incredibly against cigarettes, but I am incredibly against drugs, and I know everybody will say they're the same, but cigarettes don't rot your brain. They might kill you or damage your lungs, but they will not change your personality, and I've seen how drugs can destroy people.
Are you happy? Shamefully so. I have choice, my health and my family - and they have good health, too.
I swear by... Exercise! it can really change the way you feel and it doesn't cost anything. That and sleep - and lots of body lotion.
