Healthspan, Not Just Lifespan, Should Define Aging Progress
The piece argues that the real aging crisis is not longer lifespans but healthspan—the years lived in good health. Despite rising life expectancy, healthy years are shrinking due to chronic illness and cognitive decline, highlighting a gap between lifespan and healthspan. It spotlights McMaster University’s new Healthspan Institute, funded with $50 million from the McCall MacBain Foundation, which aims to delay disease onset and preserve physical and cognitive function through evidence-based prevention. The article also critiques wellness industry hype and emphasizes the importance of social determinants—safe streets, affordable housing, sleep, food, and social connection—in shaping healthspan, calling for early, equitable investment in prevention to reduce costly chronic diseases.
