Wellllll okay. We don't have women at every age, but we do have women from 20 to 41 -- in an attempt to show the variety of ways that women age. I've always been terrible at guessing how old people really are, and I'm betting I'm not the only one. Twenty-five can look totally different on two people, depending on diet, skincare, heredity and sun exposure (hello, Lindsay Lohan), and so can 40. But whatever your age, I think it's important not to take it too seriously -- you're only as old as you feel, after all.
