The cosmetics industry has much to answer for. It's a multi-million- pound confidence trick based on giving women endless hope, courtesy of overpriced little pots.

Every time an article is written about me or any of my contemporaries who's had the fortune and discipline to look good at a certain age, I am struck by the tone of astonishment, and the certainty that something is being done secretively to beat the devil.

I'm a fiend for costume jewellery and have countless pairs of rhinestone or diamante earrings, which are so flattering when they catch the light. I love the designers Alexis Bittar and Kenneth Jay Lane, and I always go to jewellers Butler & Wilson.

I've never chased fame. I came into this business to be a theatre actress. I was nine when I first appeared on stage. But I can't say I would turn my back on fortune. I'm someone who enjoys the benefits of money.

If you feel well and happy, your face will reflect this, but if you are down in the dumps and having a miserable time, your face will soon show this, too. In fact, you get the face you deserve by the time you're forty, and one of the keys to looking and feeling younger is being active.

You can't help getting older, but you can help yourself from becoming old and infirm, in mind as well as body.

I mean, even my dressing room at the studio has candles and cushions and cashmere rugs and things.
