Who is Robert Waldinger

The keeper of the good life

Robert Waldinger is a psychiatrist, Zen priest and professor at Harvard Medical School — and the director of the Harvard Study of Adult Development, the longest-running study of adult life ever conducted. For more than 85 years it has followed the same people — and now their children — asking a simple question: what makes a good life?

Its clearest answer surprised even the researchers. It isn't wealth, or fame, or working harder. Good relationships keep us happier and healthier. How connected and satisfied people were in their relationships at 50 predicted their physical health at 80 better than their cholesterol did.

He shared it in a TED talk that has been viewed tens of millions of times, and in his book "The Good Life." What strikes him most is how interconnected everything is: emotional wellbeing, relationships and physical health aren't separate silos — they move together.

He is also unafraid of the subject at the edge of longevity. Being reminded of the reality of death, he's found, doesn't tend to depress people — it tends to make them happier, and clearer about what matters.

Where we met

An autumn walk in Boston

We met Robert in Boston, in the autumn — he suggested a cemetery, which felt oddly perfect for a conversation about a long life. We walked among the falling leaves and talked about what eight decades of data really show about happiness, health, and holding on to the people we love.

What eight decades show

"When we're reminded of the reality of death, instead of making us more depressed, it actually makes us happier."

Robert Waldinger · Boston

Good relationships keep us happier and healthier. That's the clearest finding of the whole study.

Emotional wellbeing, relationships and physical health aren't separate silos — they're completely interconnected.

It's about building a community — we sent birthday cards, wrote thank-you notes, helped when people needed it.

Straight from the interview

From our autumn walk with Robert in Boston — what the study really found, why belonging matters so much, and what death has to teach us about living.

The finding: relationships

They didn't believe it at first. Looking back from age 80 at what they knew of people at 50, the strongest predictor of a long, healthy life wasn't cholesterol or wealth — it was the warmth of their relationships.

"The physical-health effects of good relationships were the most surprising thing we found."

Boston · from the interview

Belonging & community

The study did more than measure its subjects; it cared for them — a doctor when they needed one, a small loan, a birthday card. It made them feel they belonged, and that belonging is part of the lesson.

"They made these young men feel like they belonged to a community — and that mattered."

Boston · from the interview

What death teaches

He suggested we meet in a cemetery — and meant it kindly. Awareness of our mortality, the data suggest, doesn't drag us down; it lifts us, focusing us on the people and things that truly matter.

"People get happier as they get older, in part because they get more aware of the reality of death."

From the conversation

Robert Waldinger, in his words

Video interview

Selected passages from our conversation with Robert Waldinger — in Boston. Lightly edited for readability.

On meeting in a cemetery

Robert Waldinger"I thought meeting in the cemetery was appropriate — you're studying longevity and how we live, and it's really helpful to be reminded how beautiful it can be to be in a graveyard. One of the reasons people get happier as they get older is that they get more aware of the reality of death — and instead of making us more depressed, it actually makes us happier."

On the study's big surprise

Robert Waldinger"We didn't believe it at first. Once we'd studied people out to age 80, we looked back at what we knew about them at 50 — we had all their medical records — and asked what predicts, at 50, that you'll be happy and healthy and alive at 80. It turned out there's a very strong connection between how good our relationships are and not just how happy people are, but how healthy. The physical-health effects were the most surprising."

On building a community

Robert Waldinger"The study directors took good care of them. These were young men, and they made them feel like they belonged to a community. If people needed a doctor, a therapist, sometimes even a small loan, the study helped. We'd write thank-you notes when they returned a questionnaire, send them birthday cards. It's about building a community — and that's a big reason most of their children said yes when we asked them to join too."

On everything being connected

Robert Waldinger"We keep thinking about things in silos, but what we're realizing is that they're completely interconnected — emotional wellbeing, relationships, physical health. They don't sit apart from one another; they move together. So it stands to reason that caring for your relationships is also caring for your body."

On the talk that went viral

Robert Waldinger"I gave a TED talk and thought it would just get a few hundred views on the local channel — and then it went viral. Many people found out about the study from it, including some of the participants' children. Suddenly this quiet, decades-long study was something the whole world wanted to know about."
