The Harvard Study of Adult Development may be the longest study of adult life that’s ever been done. For 75 years, it tracked the lives of 724 men to find out about what brings happiness and good health.
There was a recent survey of millennials asking them what their most important life goals were, and over 80 percent said it was to get rich. And another 50 percent said it was to become famous. Are wealth and fame really going to get us through life? We are constantly told to work harder and achieve more. We’re given the impression that these are the things that we need to go after in order to have a good life.
What if we could watch entire lives as they unfold through time? What if we could study people from the time that they were teenagers all the way into old age to see what really keeps people happy and healthy?
We did that. To find out what is it that makes a good life, the Harvard Study of Adult Development may be the longest study of adult life that’s ever been done. For 75 years, we’ve tracked the lives of 724 men… year after year, asking about their work, their home lives, their health, and of course asking all along the way without knowing how their life stories were going to turn out.
Studies like this are exceedingly rare. Almost all projects of this kind fall apart within a decade because too many people drop out of the study, or funding for the research dries up, or the researchers get distracted, or they die, and nobody moves the ball further down the field. But through a combination of luck and the persistence of several generations of researchers, this study has survived. About 60 of our original 724 men are still alive, still participating in the study, most of them in their 90s. And we are now beginning to study the more than 2,000 children of these men. And I’m the fourth director of the study.
Since 1938, we’ve tracked the lives of two groups of men. These men were split into two groups. The first group started when they were sophomores at Harvard College. The second group that we’ve followed was a group of boys from Boston’s poorest neighbourhoods. Most lived in tenements, many without hot and cold running water.
The founders of this study would never in their wildest dreams have imagined that I would be standing here today, 75 years later, telling you that the study still continues. Every two years, our patient and dedicated research staff calls up our men and asks them if we can send them yet one more set of questions about their lives.
To get the clearest picture of these lives, we don’t just send them questionnaires. We interview them in their living rooms. We get their medical records from their doctors. We draw their blood, we scan their brains, we talk to their children. We videotape them talking with their wives about their deepest concerns. And when, about a decade ago, we finally asked the wives if they would join us as members of the study, many of the women said, ‘You know, it’s about time.’
So what have we learned? What are the lessons that come from the tens of thousands of pages of information that we’ve generated on these lives? Well, the lessons aren’t about wealth or fame or working harder and harder. The clearest message that we get from this 75-year study is this: Good relationships keep us happier and healthier. Period.
We’ve learned three big lessons about relationships. The first is that social connections are really good for us, and that loneliness kills. The survey reveals that people who are more socially connected to family, to friends and to community, are happier. They’re physically healthier, and they live longer than people who are less well connected. On the contrary, loneliness turns out to be toxic. People who are more isolated than they want to be from others, find that they are less happy, their health declines earlier in midlife, their brain functioning declines sooner and they live shorter lives than people who are not lonely. And the sad fact is that at any given time, more than one in five Americans will report that they are lonely.
And we know that you can be lonely in a crowd and you can be lonely in a marriage, so it’s not just the number of friends you have, and it’s not whether you’re in a committed relationship, but it’s the quality of your close relationships that matters. It turns out that living in the midst of conflict is really bad for our health. High-conflict marriages, for example, without much affection, turn out to be very bad for our health, perhaps worse than getting divorced. And living in the midst of good, warm relationships is protective.
For those men that we followed all the way into their 80s, we wanted to look back at them at midlife and to see if we could predict who was going to grow into a happy, healthy octogenarian and who wasn’t. It wasn’t about their middle age cholesterol levels, it was how satisfied they were in their relationships. The people who were the most satisfied in their relationships at age 50 were the healthiest at age 80. Good, close relationships seem to buffer us from some of the slings and arrows of getting old. Our most happily partnered men and women reported, in their 80s, that on the days when they had more physical pain, their mood stayed just as happy. But the people who were in unhappy relationships reported more physical pain, as it was magnified by emotional pain.
And the third big lesson that we learned about relationships and our health is that good relationships don’t just protect our bodies, they protect our brains. It turns out that being in a securely attached relationship to another person in your 80s is protective, and their memories stay sharper longer. On the other hand, those who feel they can’t really count on the other person, they experience earlier memory decline.
Those good relationships, do not have to be smooth all the time. Some of our octogenarian couples could bicker with each other day in and day out, but as long as they feel that they could count on the other when the going gets tough, those arguments don’t take a toll on their memories.
So the message that a good and close relationship is good for our health and well-being, is wisdom that’s as old as the hills. Why is this so hard to get and so easy to ignore? Well, we are human and we like quick fixes. Relationships are messy and complicated, and the hard work of tending to family and friends is neither simple, sexy nor glamorous. It is a life-long process and it never ends. The people in our 75-year study who were the happiest in retirement were the people who had actively worked to replace workmates with new playmates. Just like the millennials in that recent survey, many of our men started out as young adults and believed that fame and wealth and high achievement were what they needed to have a good life. But over these 75 years, our study has shown that the people who fared the best were the people who leaned in to relationships, with family, with friends and with the community.
So how should relationships be improved? Well, the possibilities are endless. It might be something as simple as replacing screen time with people time or livening up a stale relationship by doing something new together, long walks or date nights, or reaching out to that family member whom you haven’t spoken to in years, because those all-too-common family feuds take a terrible toll on people who hold grudges.
I’d like to close with a quote from Mark Twain. More than a century ago, he was looking back on his life, and he wrote this: ‘There isn’t time – so brief is life – for bickerings, apologies, heartburnings, callings to account. There is only time for loving, and but an instant, so to speak, for that.’ The good life is built with good relationships.
