My hypothesis is that conservative Republicans have very clear values, and when you have that, you're simply more relaxed.

You can really get poked in the back and not feel it very much, but just a feather around your lips and you really do feel it.

I've always maintained that men were more romantic than women.

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.

Why do we feel jealousy? Therapists often regard the demon as a scar of childhood trauma or a symptom of a psychological problem. And it's true that people who feel inadequate, insecure, or overly dependent tend to be more jealous than others.

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.

Any kind of novelty or excitement drives up dopamine in the brain, and dopamine is associated with romantic love.
