Some famous faces face their 40s with ease:
* Cheryl Tiegs, 44
"My age is part of me, just like I have 10 fingers and 10 toes. It seems a strange thing to try to hide or ignore. It would be dishonest.
"I feel better about myself now than ever, and I think I'm in better shape. Part of that has to do with the years I've been around and the experiences I've had. That probably shows up on my face and in my body language."
* Lisa Taylor, 40
"Beauty has been defined as one thing. It needs to be something more -- more than physical. The message women have been getting is they can't be happy unless they're gorgeous.
"I probably offer more now because I have more life experience. I was so young back then (when I was modeling in my 20s). Now I feel so much more stable and secure, and I hope what I emit is self-confidence and non-perfection.
"It's not wrinkles that make you feel old. It's the way you feel about those wrinkles. Life's too short to concentrate on getting older."
* Lauren Hutton, 48
"I'd rather talk to myself now than to the person I was 25 years ago. Just an egg, no wisdom. I am much more of a human being now than I was then and that's why we go through life. We become more valuable to society as we've dealt with problems and succeeded.
"If you can still laugh at 50 and love and feel joy and have principles, then you are somebody and that is the point of life. And I would hope that some of that would come through in my pictures. On a good day."
