Robert Waldinger: What keeps us health and happy as we go through life?
If you were gonna invest now, in your future best self, where would you put your time and your energy?
There was a recent survey of Millennial's, asking them what their most important life goals were.
Over 80% said that a major life goal for them was to get rich.
And another 50% of those same young adults, said that another major life goal was to become famous.
And we're constantly told to lean in to work, to push harder, and achieve more.
We're given the impression that these are the things we need to go after, in order to have a good life.
Pictures of entire lives, of the choices that people make, and how those choices work out for them, those pictures are almost impossible to get.
Most of what we know about human life, we know from asking people to remember the past.
And as we know, hind sight is anything but 20/20.
We forget vast amounts of what happens to us in life.
And sometimes memory is downright creative.
But 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.
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 are 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 dropout of the study, or funding for the research dries up.
Or the researchers get distracted or they die, and no body 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 90's.
And we are now beginning to study more than 2,000 children of these men. And I am the fourth director of the study.
Since 1938 we've tracked the lives of two groups of men.
The first group started in the study when they were sophomores at Harvard College.
They all finished college during WWII, and then most went off to serve in the war.
And the second group that we followed, was a group of boys from Boston's poorest neighborhoods.
Boys who were chosen for the study, specifically because they were from some of the most troubled and disadvantaged families in Boston of the 1930s.
Most lived in tenements, many without hot and cold running water.
When they entered the study, all of these teenagers were interviewed, they were given medical exams.
We went to their homes and interviewed their parents. And then these teenagers grew up into adults who entered all walks of life.
They became factory workers, and lawyers, and brick layers, and doctors.
One President of the United States.
Some developed alcoholism, a few developed schizophrenia.
Some climbed the social ladder from the bottom all the way to the very top.
And some made that journey in the opposite direction.
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.
Many of the inner city Boston men ask us, "why do you keep wanting to study me? My life just isn't that interesting."
The Harvard men never ask that question.
[laughing]
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 to 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 its about time."
So what did we learn? 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.
It turns out that people who are more socially connected to family, to friends, to community, are happier.
they are physically healthier, and they live longer than people who are less well connected.
And the experiences of 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 1 in 5 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 the second big lesson that we learned, is that it's not just the number of friends that you have,
and it't not just whether or not 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 worst than getting divorced.
And living in the midst of good, warm relationships, is protective.
Once we had followed our men all the way into their eighties, 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.
But when we gathered together, everything we knew about them, at age 50,
it wasn't their middle age cholesterol levels that predicted how they were going to grow old.
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.
And 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 eighties, that on the days that they had more physical pain, their mood stayed just as happy.
But the people who were in unhappy relationships, on the days they reported more physical pain, it was magnified by more emotional pain.
And the third big lesson that we learn 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.
That the people who are in relationships, that they really feel they can count on the other person in times of need,
those peoples memories stay sharper longer.
And the people in relationships that feel that they really cant count on the other one, those are the people who experience earlier memory decline.
And those good relationships, they don't 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 could count on the other when the going got tough, those arguments didn't take a toll on their memories.
So, this message that good close relationships are good for our health and wellbeing, this is wisdom that's as old as the hills.
Why is it so hard to get and so easy to ignore?
Well, we're human.
What we really like is a quick fix, something we can get that'll make our lives good and keep it that way.
Relationships are messy and they are complicated and the hard work of tending to family and friends, its not sexy or glamorous.
It's also life long, 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 when they were starting out as young adults,
really believed that fame and wealth and high achievement were what they needed to go after, to have a good life.
But over and over, over these 75 years our study has shown that the people who faired the best,
are the people who leaned in to relationships with family, with friends, with community.
So what about you?
Let's say your 25, or you're 40, or 60. What might leaning into relationships even look like?
Well the possibilities are practically 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 you haven't spoken to in years,
because those all too common family feuds, take a terrible toll on people who hold the 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. Thank you.
