New study questions future of human lifespan growth as longevity improvements slow

New research published in *Nature Aging* suggests that the increase in human life expectancy may be slowing down. The study indicates that the trend of living longer, seen in the 20th century, is not continuing at the same pace. Researchers analyzed data from eight wealthy countries and found that life expectancy improvements have decreased since 1990. They predict that only a small percentage of people will live to 100, unless significant advancements in slowing biological aging occur. While some experts believe life expectancy will continue to rise, the U.S. has seen a decline due to various health crises. Other countries, excluding the U.S., are still experiencing steady improvements in longevity.
