Along with our many human propensities, we evolved a huge cerebral cortex with which we make decisions.

In general, men are wired to notice obvious signs that convey interest in mating - a warm smile, for example - and ignore other subtleties, like if your lipstick is faded.

Women have never been as interesting as they are now. Not at any time on this planet have women been so educated, so interesting, so capable.

The human brain is built to compare; it's Darwinian to consider an alternative when one presents itself.

Like most animals, we're wired to associate height with power.

When people tell you to walk a certain way, it's like not thinking of a purple tomato. You can't not do it.

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.
