Study shows life expectancy growth slows in high-income countries

A new study shows that life expectancy in high-income countries is increasing at a slower rate than in the 20th century. Researchers found that people may only gain an additional 2.5 years over the next 30 years. The study, published in *Nature Aging*, indicates that humanity is approaching its life expectancy limit. While improvements in health have helped people live longer, biological aging remains a significant challenge. The research analyzed life expectancy trends from 1990 to 2019 in ten countries, revealing a slowdown in improvements, especially after 2010. The authors suggest that more focus should be placed on understanding the biology of aging to extend healthy life.
