Darius, you read my mind. This talk by Dan Buetter came up in conversation with a friend recently (https://www.ted.com/talks/dan_buettner_how_to_live_to_be_100?language=en) and I can’t stop turning it over in my mind.

The findings are remarkable, but also quite intuitive to me: those communities with highest life expectancy have a word for lifelong purpose (raison d’etre / ikigai). Oh, and as a byproduct they are happier too but it’s not their main objective. We don’t even have a word for that in our language. Perhaps we can usefully create one and spread it..
