As I get older, I find the super-skinny girls less attractive. I was looking through some woman's magazine- and I found that the women I found the most attractive had BMIs of 20-25 or so- way more than the skinny types*.

I think as women get older- especially in their late thirties- they look better at a "healthy" weight- being underweight and 38 makes you look gaunt in a way it doesn't when you're 18.

*of course, other people like skinny girls. This is just my own personal preference.
