For so many generations, a woman's only career path was to marry well and to marry up. Those days have changed.

Mothers really were not built to raise babies not only by themselves, but with only a partner. For millions of years, a woman had much more than just her husband to help rear her young... This whole idea of 'it takes a village to raise a child' is exactly how we're supposed to live.

In general, men are wired to notice obvious signs that convey interest in mating - a warm smile, for example - and ignore other subtleties, like if your lipstick is faded.

Romantic love allows you to focus mating energy. Attachment sustains that relationship as long as necessary to raise your baby.

Overdone lipstick is a deterrent to men. It rubs off easily onto their skin and the edges of their shirts, so it discourages them from kissing, touching, and coming closer to you, which is what they really want to do!

There are cognitive processes and limbic reactions associated with basic emotions. And you can change brain chemistry, but you're still not going to change memories and experiences in a human being.
