Your 2nd source is from 1990 and is at odds with the CIA World Factbook, the first source, which says that current life expectancy at birth is 80.43 in US, 79.4

Your 2nd source is from 1990 and is at odds with the CIA World Factbook, the first source, which says that current life expectancy at birth is 80.43 in US, 79.41 in Cuba: https://www.cia.gov/the-world-factbook/field/life-expectancy-at-birth/country-comparison/ https://www.cia.gov/the-world-factbook/field/life-expectancy... They're both basically similar in both years, which is astounding given the vastly higher material wealth of the US. Nice to know that both have increased a lot since 1990, though! I thought 72 sounded a bit young.
