The main characteristics of romantic love are craving: an intense craving to be with a particular person, not just sexually, but emotionally.

Men don't need linguistic talent; they just need courage and words.

Men tend to be hierarchical, but women are driven to make lateral connections so they can cooperate.

Women are naturally prone to compete over their mates.

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

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