That's not altogether surprising. But the average +10% extra lifespan is higher than I would have guessed.

I can imagine at a couple of factors that affect this.

  • Closer knit social networks (also more insular communities)
  • An increased social expectation of elder care by their family (even to extended family)
  • Shorter average height (this is a longevity asset; tall people rarely live to see 90)
  • Most of my Asian friends and their families cook from scratch on a regular basis (Asian food (not american food they buy hotdogs, burgers, and buns etc. like everyone else)

I'm not sure about the extent of correlation vs. causality.
