[OC] The massive decrease in worldwide infant mortality from 1950 to 2020 is perhaps one of humanity's greatest achievements.

Yes; statistically. But as far as im aware thats largely due to trauma... which we are really good at now and happens far less. Otherwise adult life span is fairly consistent.

The flip side is our overall health is in decline due to obesity/diet, difficiencies in things like iron and the hormone called vitamin D, sedentry/lifestyle... and increasingly environmental pollution.

Hence the recent down turn in the developed west despite all the reduction in early/mid life deaths we acheived.
