in college, i did a fair amount of number crunching on mortality statistics and the demographic transition. here’s some numbers i remember from the 1700s:
life expectancy: 40
life expectancy at age 20: 72
modern medicine has not added much to our longevity, we’ve just gotten rid of childhood mortality.
