As an American man who was born the same year that Playboy magazine was founded, let me just say that the women displayed in that mag were not at variance to my personal ideals of what a potential mate should and should not be.
Sure, those models represented a physical ideal, but so were my ideas about future careers, homes, finances, children, etc. They were all benchmarks to aim for - not guaranteed achievements. In the end, I wound up doing alright in every department (including the girl) because I just wanted the best that I could possibly attain for myself.
