Scientists have discovered that the rapid increase in life expectancy we've seen since the 20th century is slowing down. They studied data from countries like Japan, South Korea, and the U.S. from 1990 to 2019. The results show that while life expectancy is still rising, the rate has significantly decreased, especially after 2010. For instance, only about 12.8% of women and 4.4% of men born in 2019 in top countries are expected to reach 100. In the U.S., the odds are even lower, at 3.1% for women and 1.3% for men.

        Researchers like Stuart Jay Olshansky suggest that our focus on treating age-related diseases one by one is reaching its limits. He argues that instead of just extending lifespan, we should aim to improve healthspan, the years we spend in good health. He also warns against exaggerated claims in the anti-aging industry, saying we should be realistic about the possibilities.

        Olshansky believes we're already benefiting from medical advances, but these come with the downside of age-related diseases like heart disease and cancer. He's optimistic about future breakthroughs in geroscience, which could help delay aging more broadly. However, he emphasizes that the goal should be healthier lives, not just longer ones.
