We live well enough to have the luxury to get ourselves sick with purely social, psychological stress.

We’ve evolved to be smart enough to make ourselves sick.

It's great to have a buff frontal cortex to do that harder thing - for example, help a person in need rather buy some useless, shiny gee-gaw.

Almost always, genes are about potentials and vulnerabilities rather than about determinism.

There's the complex categorization of low warmth/high competence. This is the hostile stereotype of Asian Americans by white America, of Jews in Europe, of Indo-Pakistanis in East Africa, of Lebanese in West Africa, of ethnic Chinese in Indonesia, and of the rich by the poor most everywhere. It's the same low-high derogation: They're cold, greedy, clannish - -but, dang, they're sure good at making money and you should go to one who is a doctor if you're seriously sick.

How much you groom somebody else is more important than who grooms you.

We are just another primate but a very confused, malleable one.
