The 40s onwards are when we can really begin to enjoy ourselves. For many women, this is when everything comes together, and they look better than ever. The great thing about getting older is you don't have to do/wear/say anything you don't want to. It wasn't until my very late 30s that I stopped worrying about what other people thought.

Wearing a bold print gets harder as you get older. Its safer to stick to subtle prints or block colours. I have always found prints quite tricky. My daughter Carly, who is on the design team at Stella McCartney, is obsessed with them.

I like to get on with people. I don't go around being nasty, but if someone crosses me, I can be horrible back.

Being young isn't about age, it's about being a free spirit. You can meet someone of 20 who's boring and old, or you can meet someone of 70 who's youthful and exciting. I met Fred Astaire when he was 72 and I was 21, and I fell in love with him. He certainly was a free spirit.

Christianity, like most religions, works with fear. Sins can be confessed and you are 'Clean again' and can start to sin again without thinking about your old sins. We believe that people should ask themselves why they sinned. They should show some responsibility.

I love exercise but I find it boring doing the same thing all the time, so I fluctuate between going to the gym, doing Pilates and taking dance lessons.

I think everyone should sing - it's so good for you, as it makes you breathe deeply, and it's good for you emotionally, too. It's a brilliant release way of lifting the spirits.
