Women have a better sense of smell than men do, and it's even sharper in the middle of their menstrual cycle, when estrogen levels peak and women are more likely to be deciding whether a man's attractive.

Psychologists maintain that the dizzy feeling of intense romantic love lasts only about 18 months to-at best-three years

Anthropologists have found evidence of romantic love in 170 societies. They've never found a society that did not have it.

We still have community, but we don't seem to have local community. Even in a small town where you know your neighbors and your mother's down the street, they're not in arm's length.
