What makes life truly meaningful? According to one of the world’s longest- running studies, it all comes down to relationships.
The Harvard Study of Adult Development has followed participants for more than 80 years, and its findings are clear: strong, positive social connections are the single most powerful predictor of happiness and health as we age.
Led by Dr Robert Waldinger, a psychiatrist at Harvard Medical School, and Dr Marc Schulz, a psychology professor at Bryn Mawr College, the research has tracked the lives of hundreds of individuals – first Harvard undergraduates and boys from disadvantaged Boston neighbourhoods, later expanding to include their families across generations.
Their bestselling book The Good Life distils decades of data – from medical records to heartfelt interviews – into one resounding message: “Good relationships keep us happier and healthier. Period,” Dr Waldinger said.
It turns out that it’s not wealth, success or even physical fitness that gives us a fulfilling life – it’s the quality of our relationships. Emotional support, social bonds and a sense of belonging impact not just our mood, but our brain function, physical health, and even how long we live.
Importantly, it’s never too late to make a difference. “At any age, we can make small choices that strengthen our relationships,” Dr Waldinger said.
Whether it’s a friendly chat or a shared meal, every connection counts.
For older adults, these insights are both uplifting and practical.
