Throughout the 20th century, and average physique for a woman was ideal. In the 20s-30s, women with big breasts were thought to be "fast", so women didn't want to have big breasts...
W. African men like their women BIG as it's a sign of health---good eating. But as we know, it's not healthy...
Even back in the days of the Scarlet Letter, a attractive woman had curves---but was slender.
Men today are influence by the "supermodel" look, which was created by women and gay me to nullify womanly attributes like breasts and hips---women don't like competition, while men welcome it. Women get rid of competition by getting rid of certain attributes like prettier faces and breasts and ass, all the things that men like.
we ve been subconsciously conditionned by pictures we ve been watching everyday since our childhood. Had we been conditionned to see different models, pcitures of women, had we been conditionned to believe, in others values, we would nowadays think differently. Funny isnt it?
All of this being the result of watching tv hours a day for decades.
TV can be a great learning tool, but look, it's a machine to sell using the most advanced knowledges in biology and psychology in humans. 99.9% of what you watch on tv exists to sell something.
