I'd like to start giving people the option of commenting on shorter Cold Takes pieces (which I don't cross-post here or provide audio for). I'm going to use this post for that: I will generally leave a comment for each piece, and people can leave their comments as replies to that.
I think one might find that those living in small agricultural/animal herding communities also report high levels of satisfaction with their lives, perhaps as a result of the lifestyle/social structures described by lincolnq above, and they don't have to sacrifice modern medical care, comfortable beds, a steady supply of food etc. A hunter-gatherer lifestyle is not a prerequisite for those kinds of structures and relationships. I'm thinking of the Sardinian communities in the central plateau of Sardinia, which has very high numbers of very long lived people. Of course, those communities are now predominantly old, with young people by seduced by the money, more material goods, and "action" of the large cities. So, there's that to consider as well. When there's a choice, young people prefer to leave.
