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.

I don't look my age, I don't feel my age and I don't act my age. To me age is just a number.

I don't believe in eating junk and I protect my face all the time from the sun, even in the winter with base and makeup.

And sometimes when I would get in the morning, when we'd go out - we'd see shrapnel and bits of stuff in the streets and bombed buildings, and - but I was evacuated a lot. Every time the blitz got heavy, my parents would take us off to the country.

When I was 49, I posed for Playboy - I was very flattered to be asked. I was quite honoured, really, considering that most of the models they feature are in their twenties.

It is unseemly to undress on stage. I won't do that.

I consider you as old as you look and feel. And in that case I feel - I feel I'm about 39, like Jack Benny.
