Human life expectancy dramatically increased last century. Compared to babies born in 1900, those born at the turn of the 21st century could live, on average, three decades longer—with many living to celebrate their 100th birthdays. In other words, for much of the century, each passing year added something like three months to a person’s potential time on Earth. To optimists in the longevity field, the rapid rise in life expectancy will likely continue at a steady, if not accelerated, pace.
Others have a more pessimistic view. In their predictions, humans will hit a natural ceiling, with the average person in developed countries living to an age far less than 100. A new study adds to the debate with analysis of data from 1990 to 2019. After examining life expectancy from eight countries with the longest living populations, plus those from Hong Kong and the US, the team reached a troubling conclusion: Despite innovations in healthcare, the increase in overall life expectancy is slowing down.
