Just commenting on what Sunny's twin thing.....From personal experience.

I have a cousin-in-law, who was always slender and very pretty (how my cousin married her I don't know....) Anyhow, when she reached 40, she had a mid-life crisis of sorts. Went low fat, lost weight, etc. It wasn't even that she needed to lose weight but she did anyway. She's so thin now that she can wear Junior sized clothing (and does......by the way, the stuff Miley Cyrus wears doesn't look quite right on a 47 year old woman!) She's totally happy that she can wear the same sized clothing a 13 year old can. BUT, she looks way older than 47. She looks like she's in her mid-50s. Not only does she have wrinkles on her face, the skin on her arm, neck and upper chest look wrinkled and loose too. She also has a perpetually tired look (no other way I can describe it), so that she looks worn and weared out. I met her sister at a family function last year. The sister is 2 years younger and she looks her age---no extreme wrinkles, doesn't look worn out.

So I think that when you get older, it's probably better to keep your weight in the mid-upper "healthy" BMI range. All the wrinkle and aging tv shows say that the wrinkles are due to the lack of collagen. But maybe it's a combo of the lack of collagen and fat?
