What our grandmothers told us about playing hard to get is true. The whole point of the game is to impress and capture. It's not about honesty. Many men and women, when they're playing the courtship game, deceive so they can win. Novelty, excitement and danger drive up dopamine in the brain. And both sexes brag.

When you massage someone, the levels of oxytocin go up in the brain, and oxytocin is one of the chemicals that drives attachment.

Liberals and conservatives are looking for entirely different things. Their attitudes toward romance and how they court are really dramatically different. There's almost no overlap.

Real competition can drive up testosterone, which boosts libido.

Today, American women bear an average of 2.2 children that live to adulthood. Across most of Europe, women bear even fewer young.

There were real reasons that you were attracted to somebody originally. The brain doesn't pick willy-nilly. Unless you part ways hating each other for some reason, that mechanism could get triggered again. You can literally fall in love again.
