A recent US study revealed that humans are unlikely to see substantial lifespan increases this century, as life expectancy growth has slowed over the past 30 years in countries with the highest longevity, such as Japan.
The study conducted by a team from the University of Illinois and others, published in the US scientific journal Nature Aging on Oct. 7, suggests that “survival to age 100 years is unlikely to exceed 15% for females and 5% for males.”
“Unless the processes of biological aging can be markedly slowed, radical human life extension is implausible in this century,” according to the study.
The average increase in life expectancy from 1990 to 2019 in Hong Kong and the eight countries with the longest-lived populations, including Japan, South Korea, and Switzerland, was 6.5 years, the study explained.
According to the study, while human life expectancy at birth increased by nearly 30 years in high-income nations over the course of the 20th century, largely due to advances in public health and medicine, overall improvements in life expectancy have slowed since 1990.
