Curator/Sister Y read of the theory that lactose/gluten tolerance evolved so we would put up with civilization and asked if there was evidence “Northern Euros and Tuaregs more blissed-out, docile, and civilization-adapted than Asians”. I don’t know the answer, but it might be found in a World Value Survey (they have questions about feeling restless) or some Pew Global Research. I’ll try and look into it later.

On that sort of subject, kudos to n/a for pointing out some data that corrected the Audacious Epigone (no slouch himself).
