Everything you can find says the opposite? How odd! When I search “china usa life expectancy” on DDG I get a page that’s choc-a-bloc with headlines about the provisional CDC release that says all signs point toward US Covid death rates causing such a sharp drop in US median lifespans that China, already having shown stunning improvements this past few decades and recently nipping at the US’s heels, has now pulled ahead.
Where did you hear that? Everything I can find says the opposite.
