A tragedy, that we've adopted such an unrealistic cultural ideal that the girls of today feel like they need to adopt an anorexic lifestyle in order to conform to a standard that is only possible to achieve with the assistance of photo manipulation, and can only be approximated with plastic surgery and starvation.
The girls most concerned with their appearance are responding out of fear of your disgust, San. I'd rather we teach our daughters to love and respect themselves (including respecting their physical health), and to insist on being with people who will hold them in the same esteem.
Not someone who will shame them for their inability or unwillingness to conform to an unnatural ideal that defies the dictates of biology. Frankly, I'd rather they be overweight. At least that would screen out the misogynist bigots who deign to be with them only because of the way they look.
Nobody can stay twelve forever, you know. Though they might approximate it for awhile, biology and age catch up despite one's best efforts.
And where would a partner like you be then? The teen modeling shows?
