" In his book Human Universals, Donald E. Brown lists traits that people in all places share. The list goes on and on. All children fear strangers and prefer sugar solutions to plain water from birth. All humans enjoy stories, myths, and proverbs. In all societies men engage in more group violence and travel farther from home than women. In all societies, husbands are on average older than their wives. People everywhere rank one another according to prestige. People everywhere divide the world between those inside their group and those outside their group. These tendencies are all stored deep below awareness. "
