Overview
- The study, published in Nature Aging, indicates that life expectancy improvements have slowed in countries with the longest-living populations.
- Researchers found that since 1990, the average lifespan in high-income nations has only increased by 6.5 years.
- The United States shows particularly slow progress, with life expectancy gains nearly stagnant due to factors like drug overdoses and obesity.
- Experts argue that without breakthroughs in slowing biological aging, further significant life extension is implausible.
- The study emphasizes the need to focus on extending healthy life years rather than merely increasing lifespan.
