When we talk about living long, we often think first about exercise and diet. But Ken Stern — who has spent years studying the economic, social, and lifestyle aspects of aging — intentionally started elsewhere.
In his latest book (Healthy to 100) and a CNBC feature, he explored what truly keeps people active, healthy, and mentally sharp over the long haul. His findings point to something deeper: it’s about relationships, how we view work, and living with clear purpose.
His research overlaps with the well-known Blue Zones insights. Stern studied Japan, South Korea, Singapore — and closer to home — Italy and Spain. These countries consistently outperform places like the US or Hungary in healthy life years. They’re not perfect, but that’s exactly why they make such great case studies.
If it works where it’s tough, why not here?
Singapore is hot, crowded, and high-pressure; Spain struggles with obesity and smoking; Japan faces rapid aging; South Korea battles intense work culture. These challenges aren’t far from what we experience here in central Europe, Hungary. Plus, many people here work past 60 out of necessity, not choice or enjoyment. Meanwhile, the sandwich generation juggles work, aging parents, and teenage kids. Stress often brings irregular meals, lack of exercise and sleep, and the feeling there’s no time to slow down. Stern’s experience shows it’s not perfect conditions that matter most — it’s how a society responds.
Aging Isn’t an End, It’s a New Beginning
One of Stern’s key insights was that aging isn’t tied to a specific number. Sixty or 65 isn’t a cutoff — retirement marks a fresh chapter. Stern realized this in his own life: after 60, he saw realistically 20 more active years ahead, and he wanted to live them intentionally, not just drift.
He used to help shape others’ stories, then realized he had his own to tell. He writes books, hosts podcasts, creates content — not out of obligation, but because he feels useful and believes the next 20 years can be just as meaningful as the last. This revealed a vital truth about longevity:
It’s not about how old you are, but whether you still have plans, purpose, and a place in the world.
Work, But Not Out of Obligation
In Japan, Stern met older adults working part-time alongside their pensions — in candy factories, accounting, or as tour guides. He noticed that while they earned some extra cash, they also gained strength from their work: their tasks gave structure, social connections, and self-worth.
This stands in sharp contrast to many experiences here, where work often feels lifelong, exhausting, and just a survival tactic.
Stern says the real question isn’t whether we work as we age, but how. Instead of all or nothing, there’s a sustainable middle path — and where it’s missing, society should build it.
When Generations Truly Connect
In Japan and South Korea, Stern saw community spaces where age groups aren’t separated, unlike what’s common here. In Kanazawa, older adults teach, volunteer, and spend meaningful time with youth and people with disabilities. Across countries, he found that intergenerational connections are a deliberate strategy, not just a nice gesture. Research shows this boosts mental and physical health, reduces isolation, and restores the feeling of being useful — something modern societies often take away too soon.
Spending time together benefits all ages: younger generations gain stability, role models, and life wisdom from elders. Connection eases generational anxiety, breaks isolation, and helps us see aging not as decline, but as a different way of living.
Connections Beyond the Screen Noise
In Italy, Stern was struck by how different the pace of togetherness is. Meals aren’t rushed, phones rarely appear during shared time, and conversations feel more genuine and deeper.
Decades of Harvard research show that quality human relationships matter more for a long, healthy life than money or career.
Stern believes one of modern society’s biggest challenges isn’t lack of information, but that we’re rarely truly present in each other’s lives.
Learning as Long as There’s a Why
In South Korea, lifelong learning is a constitutional value, and this mindset was clear everywhere Stern looked. He realized learning keeps the mind sharp and builds community — especially when it happens in person, not just online. Gaining new skills, staying curious, and connecting with others form a mental safety net that helps us adapt to life’s changes.
What’s the takeaway? Stern says longevity isn’t about miracle cures or strict diets. It’s about how a society nurtures human connections. Happy aging doesn’t require perfect conditions — it needs real-world solutions that give meaning to every stage of life.
