I've always been unhappy with my teeth. I've lost most of them from my bottom jaw, and those in the upper jaw have been screwed in or capped. As a result, I've got great hollows under my cheeks, and my bone structure seems accentuated.
Probably the only type of cosmetic surgery I'd consider is having my bust reduced. It's alright for my current role in 'The Marquise' because it's a costume drama, which means boned corsets and a bit of cleavage, but it's a drag otherwise.
I'm actually quite a nice person. It's to do with the way I look, an uncompromising sort of face, brusque delivery and voice, and I think the combination of all that. When I'm doing pantomime, children will scream the place down before I open my mouth. There's obviously something that really gets them.
Because my career has been based so much on my looks, when I finally pass my 'sell-by' date, I think I'll probably pack it in. Unless I make the changeover into playing witches or something, I don't see what career I can have.
I never drink cow's milk; I always opt for the soya alternative, and when I eat most dairy products, it tends to be in extremely small doses. However, being a vegetarian means I have to get protein from somewhere, so I do eat eggs and cheese about once a week.
I have tried Botox, and I don't like it because it stops you being able to move your facial muscles which, as an actress, are essential. But I do have collagen injections.
I'm still a size 10, but it's the toning that's getting me down, and I think it can only get more difficult as I get older. Either one gets very thin and scrawny, or one puts on poundage; I'm definitely not going to pile on the pounds, so I can expect to end up scrawny.
I have white hair now, but a lot of it, and I'm still very glamorous, and so I won't disappoint, I hope! I'll still be wearing the tight leather trousers and high-heel boots, regardless of what age!
When eating out while on tour, a great place to get vegetarian food is Thai restaurants, as they have lots of options. I absolutely adore salad and vegetables - I will eat salad until it's coming out of my ears. Although I think it's great in any form, my particular favourite has to be beetroot salad.
I am fortunate in having this bone structure because I have a tremendously prominent temple. I like to think that's it's because I'm so intelligent. People say: 'You haven't got a line on your forehead.' I do. It's just the bones are holding them all out, and the cheekbones are holding my face up.
Whenever I get on stage, I feel safe and in control. Life can be so uncertain, but on stage, I always know how a drama or crisis is going to end. Acting is a great comfort blanket and has gotten me through countless personal crises. I am a firm believer that the show must go on.
If you put a much older woman in 'Doctor Who,' they can identify with it. I think it's quite an interesting concept, and if you remember things like 'Grimm's Fairytales,' the older woman is often the villainess, often the terrifying figure - why I do not know, but often she is. I think it's an idea to be exploited.
I was asked to do 'I'm A Celebrity Get Me Out Of Here,' and I said: 'No thank you.'
I used to play a lot of foreign women in my youth because I was prettier then. I would go for interviews, and directors would look at these sultry, exotic looks, hear this clipped accent and think the two don't go together. So they would give me a foreign accent.
I love the Wendy Syred boutique in Taunton. She has fantastic off-the-wall stuff, such as Vivienne Westwood. And I always have huge success in Omah Shoes, which is also in Taunton. I've got such small feet - three and a half - but I always find my size there.
