FYI: For most of civilized history, life expectancy fluctuated in the 30 to 40 year range.
Child mortality was all too common, and even for those that made it to adulthood, a long and healthy life was anything but guaranteed. Sanitation was poor, disease was rampant, and many medical practices were based primarily on superstition or guesswork.
By the 20th century, an explosion in new technologies, treatments, and other science-backed practices helped to increase global life expectancy at an unprecedented rate.
From 1900 to 2015, global life expectancy more than doubled, shooting well past the 70 year mark.
