I have always had trouble guessing someone's age by his or her looks, and no one can ever guess mine if they don't know me. I know this because when I say something like "Oh, I've been married for 23 years" they say "What, were you ten????!!" and had a friend I met at a convention and was emailing me tell me I must be wrong when I emailed her on my birthday - she asked if I had made a typo. Yet when I was a college freshman, I had people somehow convinced that I was older than 18, I guess because I just wasn't ditsy. So it is much more the attitude, I have found, than anything that matters. Also, as a pale person, I never did go out an "tan" like many of my friends, so I don't have the sun damage they do. I think I look my age, but some people I know look older than our age. I guess my skin is just part of the blessing/curse of my English and Swedish heritage - made for cold and fog, but holds up pretty well! Great Aunt Bertha was far less wrinkly that others who were decades younger than her in the nursing home when she was 92!
