Well, I for one can say I am fighting it every step of the way. I'm 37 & during the last few years my age has started to show--it's amazing how it happens so quickly! Almost overnight I had crow's feet, frown lines, all kinds of crap that make my heart sink when I see them.
Anyway, I spend oodles of money on moisturizers, hair care products, anything I can find that'll slow the aging process. I'm in the process of going through a minor cosmetic procedure to mitigate the smoker's wrinkles around my mouth. I'm starting my very own "plastic surgery savings account" so in 10 years I can do the full face.
Yes, I work out hard, yes, I diet a lot, yes, I try to lead a healthy lifestyle. But there are some things that are simply beyond our control--the aging of the skin (controlled somewhat by staying out of the sun & staying away from smoking, but it's too late for me now), changes in metabolism, etc. etc.
So, Lori, what I'm trying to say is you are not alone. I keep looking to women like Madonna, Cher, Jane Fonda, to reassure myself that I can still be beautiful in 20 or 30 years, but the whole prospect just scares the daylights out of me.
