The Limits of Human Longevity: Why Immortality Remains Elusive

A study published in Nature Aging suggests that human lifespan may be nearing its biological limit, with a maximum achievable age between 115 and 120 years. While life expectancy has increased due to healthcare advancements, its growth is slowing, and immortality remains unlikely. Countries like Hong Kong and South Korea have seen life expectancy rise due to effective public health policies, while the U.S. faces declines due to issues like the opioid crisis. The focus of medical research may need to shift from extending lifespan to improving the quality of life for the elderly.
