I don't understand people getting depressed about getting older. There is nothing you can do about it, so you might as well embrace it.

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.

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.

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.

It's hard to see how anyone can fail to care about innocent children and animals being blown up by landmines.

Life is about making choices: you can either spend three quid on a glossy magazine or you can spend it clearing three square metres of minefield and help give people their lives back. As simple as that.
