Staying Healthy as We Age

|

,

A recent editorial collection from Time magazine’s Future of Living series features an insightful article on how to age well, centered on lessons from one of the longest-running public-health studies in the world.

I came across an article in this series in which Time correspondent Veronique Greenwood interviews Dr. Donald Lloyd-Jones, an epidemiologist and at Boston University Chobanian & Avedisian School of Medicine, who is also the current head of the Framingham Heart Study, about what decades of research reveal about healthy aging and longevity.

Genetics are not destiny. We can actually bend that curve, and people can do better if they can pursue these healthy lifestyle options.

– Dr. Donald Lloyd-Jones in Time Magazine

The discussion also highlights how long-term data from Framingham underpins modern strategies for preventing chronic diseases and suggests actionable ways people can improve both their lifespan and healthspan.

Below are some of the key takeaways from Dr. Lloyd-Jones’s interview, which focuses on healthy aging and science-backed methods to live longer:

Article Series

  • Science-backed habits that promote longevity
  • Staying Healthy as We Age (you’re here)
  • About the Framingham Heart Study: The Framingham Heart Study began in 1948 in Massachusetts to understand rising rates of heart disease and has since enrolled three generations of participants. Over more than seven decades, it has become one of the foundational sources of knowledge on not just heart health but aging across multiple organ systems, from the brain to kidneys.
  • What the Study Revealed: Early data showed strong connections between cardiovascular risk factors — such as blood pressure, cholesterol, smoking, weight, and physical inactivity — and disease outcomes. Over time, researchers expanded what they measure: genetics, epigenetics, proteomics, and more. These rich datasets enable nuanced views of how lifestyle shapes health decades down the road.
  • “Life’s Essential Eight” reduces the risk of aging diseases : Drawing from decades of evidence, the American Heart Association’s Life’s Essential Eight serves as a comprehensive, evidence-based set of health behaviors and measures linked to lower risk of aging-related diseases.
    • Healthy diet
    • Regular physical activity
    • Avoidance of all nicotine exposure
    • Healthy sleep patterns
    • Maintaining a healthy weight
    • Healthy blood pressure
    • Healthy blood sugar
    • Healthy blood lipids
    • These factors are modifiable and have been shown to reduce the incidence not only of cardiovascular disease but also dementia, cancer, arthritis, and other chronic conditions of aging. Lloyd-Jones stresses that focusing on these foundational habits helps optimize both lifespan and healthspan — meaning not just more years, but more healthy years.
  • Societal Challenges and Success Stories: While the science has been clear for decades, implementing these insights broadly remains a challenge. The environment we live in — from food systems to urban design — often undermines healthy choices, making preventive strategies harder to adopt at scale. A notable success story: Finland dramatically reduced coronary heart disease mortality by applying public-health policies informed by Framingham research — from tobacco control to dietary shifts — resulting in an 84% decline in death rates over 30 years.
  • The Power of Lifestyle Over Genetics: One hopeful finding highlighted near the end of the interview: lifestyle factors can override genetic risk. In a descendant study, individuals with high-risk genes but healthy lifestyles lived, on average, 12 years longer and 19 more years free of cardiovascular disease compared with peers with poor lifestyle habits.

This reinforces a critical theme of the article — that while our genes are a piece of the puzzle, our daily choices matter immensely when it comes to aging well.
