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.

Most of us don't collapse into puddles of stress-related disease.

But often, it's easier to resist temptation with distraction, or to be so inculcated in doing the right thing that it's automatic, outside the frontal cortex's portfolio - Then it isn't the harder thing, it's the only thing you can do.

Until you appreciate something crucial - It is incredibly easy to manipulate us as to who counts as an Us, who as a Them.

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

If you care about your longevity and health, be a socially affiliated baboon who is better than high-ranking ones at walking away from provocations.

We're getting along so well; I trust you so much for this one second that I'm going to let you yank on me.
