A recent report makes surprising claims about the causes of the apparently impressive Cuban life expectancy data.
It says that shortages of cars, food, and reduced cigarette use had effects that were on balance healthy (I don’t see anything specific about whether a cigarette shortage caused the decline in smoking).
I had thought that there was strong evidence for the claim that increased wealth reliably correlated with increased health. It looks like I ought to examine the evidence on that subject more carefully.
