Eric Topol on Keys to Longevity

We are living in a strange moment for growing old. On one side, there is a booming industry of biohackers plunging into ice baths, influencers hawking peptide supplements, and tech billionaires pouring enormous sums into chasing something close to immortality. On the other side, there is the actual science — and according to one of the world’s most respected cardiologists and longevity researchers, the two sides have very little in common.

Dr. Eric Topol, founder and director of the Scripps Research Translational Institute and author of the book Super Agers, appeared on NPR’s TED Radio Hour on May 1, 2026, to do something rare in the longevity space: separate what actually works from what is being sold to us. His conclusion is both refreshing and empowering — especially for older adults who have been watching the anti-aging industry explode and wondering whether any of it applies to them.

The short answer, according to Topol, is that the most powerful tools for living a longer, healthier life are not found in a supplement stack or a cold plunge tub. They are found in habits — and they are available to everyone, regardless of age, income, or genetics.

The Number That Should Change How You Think About Aging

Topol opens with a statistic that reframes the entire conversation about aging. The average American lifespan is 79 years. But the average American healthspan — the years lived free from major chronic disease — is only 64. That is a gap of 15 years during which most Americans are living with significant illness, disability, or decline.

This distinction — between lifespan and healthspan — is the lens through which Topol believes we should be evaluating everything in the longevity conversation. The goal, he argues, is not simply to live longer. It is to compress that 15-year gap: to stay healthy, active, and free from major disease for as many of those later years as possible. And the science, he says, gives us real tools to do exactly that.

What Topol’s Research on “Super Agers” Actually Found

Topol’s research at Scripps began with a straightforward question: what do people over 80 who have never developed a major chronic disease have in common? He called these people “Super Agers” and studied their DNA, looking for genetic advantages that set them apart. What he found surprised him. While some genetic factors play a role, the gap between Super Agers and the general population is not primarily explained by lucky genes. It is explained, to a substantial degree, by lifestyle.

This is the most important takeaway from his work — and the most hopeful one. You do not need exceptional genetics to dramatically improve your healthspan. And critically, Topol told NPR, it is never too late to start. Evidence suggests that lifestyle changes made even in midlife can add meaningful years of healthy living. The compounding benefits of good habits do not have an expiration date.

The Habits That Actually Work

When Topol lists what the evidence actually supports, it is a striking contrast to the products being marketed in the anti-aging space. His list is not glamorous. It does not require expensive supplements or extreme protocols. But it is grounded in some of the strongest evidence in medicine:

The Honest Warning About the Anti-Aging Industry

Topol is direct about the anti-aging marketplace in a way that is unusual for someone of his stature. Whether it is cold plunges, protein-maximizing diets, or experimental peptides being promoted by influencers online, he sees a marketplace growing far faster than the evidence can keep up with. Specious claims about unregulated products, he says, are simply out of control.

His guidance is clear and worth repeating: be wary of optimization fads. Stick to evidence-based recommendations — not what he pointedly calls “eminence-based” opinions, meaning ideas promoted by high-profile personalities rather than scientific research. Invest in habits, not miracles. The anti-aging industry is very good at making its products feel urgent and exclusive. The science says the most powerful tools are neither.

It’s Not About Your Genes — and It’s Not Too Late

Perhaps the most meaningful thing Topol says — the thing that makes this NPR conversation genuinely good news — is the repeated emphasis that healthy aging is not reserved for people with lucky DNA or elite resources. The Super Agers he studied were not primarily distinguished by their genetics. They were distinguished by their habits.

Getting older, Topol argues in his book Super Agers, does not have to mean passively waiting for decline, or believing that your ancestors’ fate predicts your own. It is something you can shape. Not immortality — but more vibrant, more enjoyable, more fully lived years. The habits he describes are the same ones woven through the research covered in this Good News on Aging series: move your body, sleep deeply, stay connected, protect your hearing and vision, and don’t let fear of your family history convince you that your choices don’t matter. They do.
