At first I assumed hate was the opposite of love. But it isn't. The opposite of love is indifference.

In courtship, who wins and who loses will determine who passes on their DNA to tomorrow.

Nobody gets out of love alive. You turn into a menace or a pest when you've been rejected.

A woman of 40 or 50 or 60 can take estrogen replacements, get facelifts, spend her money in bars.

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

Women like signs of money and education - things that indicate that not only is this guy going to have some resources, but he's also willing to share them.

There's all kinds of reasons that you fall in love with one person rather than another: Timing is important. Proximity is important. Mystery is important. You fall in love with somebody who's somewhat mysterious, in part because mystery elevates dopamine in the brain, probably pushes you over that threshold to fall in love.
