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

Romantic love is an obsession. It possesses you. You lose your sense of self. You can’t stop thinking about another human being.

Men and women are like two feet; they can help each other get ahead.

Saliva has testosterone and estrogen. When you kiss, you're having a chemical experience.
