If you had to make one choice right now to invest in what would keep you happy and healthy as you go through the rest of your life, what would that investment be
0:12
Most of us think it's something to do with getting rich or achieving a lot to have a happy, healthy life
0:20
But the single choice we can make that's most likely to keep us on a good path of well-being is to invest in your relationships with other people
0:32
The people in our 85-year study who stayed the happiest and the healthiest were the people who had the warmest connections with others
0:42
Most research that's been done is done on what goes wrong in human development so that we can help people
0:49
But this was a study of what goes right. I'm Robert Waldinger

I am a psychiatrist, and I'm professor of psychiatry at Harvard Medical School

All right, now back to the video. I am the fourth director of the Harvard Study of Adult Development, and it is the longest study of adult life that's ever been done
2:27
It started in 1938. Oldest of Harvard's professional schools is the medical school
2:34
This study set out to understand what makes people thrive as they grow and develop
2:41
And it has followed the same people throughout their entire lives, from the time they were teenagers all the way into old age, then began to include their wives and eventually all their children
2:55
Now there are over 2,000 people in these 724 families who we have followed year after year after year
3:04
We started collecting information by giving elaborate psychological examinations, also medical examinations
3:14
Then we went to their homes. We talked to their parents and sometimes even their grandparents
3:19
The workers made elaborate notes about what was being served for dinner and what the discipline style was in the family and even what the curtains looked like
3:27
And then, eventually, as new methods of studying human life came on board, we adopted those methods
3:35
So, audiotaping, videotaping. DNA wasn even imagined in 1938 when the study began But we now draw blood for DNA And we put many of our people into an MRI scanner and watched how their brains light up
3:52
as we show them different visual images. We bring them into our laboratory
3:57
and we deliberately stress them out. And then we watch how they recover from stress
4:03
as one more way of understanding well-being. So we've learned several big lessons
4:10
about relationships, about good relationships. One of them is that childhood experience really does matter
4:21
What happens to us in childhood sets the stage for what we come to expect from the world
4:29
That's often a good thing if we're raised by people who are warm and caring and reliable
4:35
But some people are raised in environments where they feel like the people who are supposed to take care of them aren't trustworthy, can't be
4:43
relied upon. And so many of those people come into adulthood with the expectation that the world is
4:51
not a safe place. Well, it turns out, our study shows, adult experience can correct for some of
4:59
those unfortunate lessons that people learn in childhood. Becoming connected with a good partner
5:06
with good friends who you can count on can go a long way to change those gloomy expectations
5:13
about the world and about relationships. Another lesson that we learn is that all relationships
5:21
that are important have some disagreements or some difficulties. Actually, facing those difficulties goes a long way to strengthen relationships much of the time
5:36
It's normal to have disagreements. It's normal to have difficulties. And the more skill we can develop in working through difficulties
5:44
the better our social worlds are. And finally, one of the biggest lessons is that our connections with other people
5:54
help us weather the hard times of life. And hard times are there in every life
6:01
Our original participants were born during the Great Depression, and many were of an age to go and serve in World War II
6:08
And when we asked them, how did you get through these really difficult times
6:14
All of them, to a person, talked about their relationships. Our neighbors shared what little we had during the Depression
6:22
My fellow soldiers in the trenches were the people who kept me going
6:27
The letters that came to me from back home while I was overseas in the war
6:31
were what sustained me. And so what we find is that these connections turn out to be the best protection against the difficult times that are always coming our way
6:45
We know that the physical effects of positive relationships are very different from the physical effects of loneliness or of actively unhappy acrimonious relationships
6:59
The best hypothesis about how relationships get into our bodies and affect our physical health is through stress
7:09
When we're stressed, the body is meant to go into what we call fight or flight mode
7:15
where essentially heart rate goes up, might start to sweat, a variety of changes happen
7:21
But then when the stressor is removed, the body is meant to return to equilibrium
7:27
If I have something stressful happen during the day and I can go home and talk to a friend or call someone I can literally feel my body calm down
7:39
If I don't have anyone I can talk to, we believe what happens is we stay in a kind of low-level chronic fight-or-flight mode
7:49
And what that means is that we have higher levels of circulating stress hormones like cortisol
7:55
We have higher levels of inflammation going on in the body. And these changes gradually wear away different body systems
8:06
which is how stress and loneliness could make it more likely that we would get coronary artery disease or type 2 diabetes or arthritis
8:18
It could affect multiple body systems through this common denominator of chronic stress
8:25
Loneliness is certainly a stressor, but research also shows us that ongoing acrimony in a relationship
8:35
constant arguing and unhappiness is also hazardous to our health for just the same reasons
8:43
A toxic relationship is one where we can't get beyond difficulties, unhappiness, anger
8:51
We can't ever come out the other side to a place where we're okay again with each other
8:58
And so a toxic relationship involves unhappiness, even if you're quiet about it
9:04
Chronic resentment, often withdrawal, and then active arguing. Staying in a really toxic, intimate relationship may be worse than splitting up
9:17
because a really difficult, acrimonious relationship is that source of chronic stress that breaks down our body systems
9:27
On the other hand, couples argue all the time without having these detrimental effects
9:34
What we've found from our research is that couples can argue often and quite vocally
9:42
but if there is a bedrock of affection and respect, those relationships continue to be positive and stable
9:52
Good relationships are emotion regulators. Being connected to another person makes us feel safer
9:59
and keeps our bodies at a kind of physiologic equilibrium that promotes health
10:09
We know that maintaining our physical fitness is an ongoing practice. And what we found was that our happiest, healthiest people did the same with their relationships
10:22
When we looked at all these lives and how they played out over time
10:26
we found that the people who were the happiest and the healthiest were inviting people over
10:33
They were joining clubs. They were maintaining connections with family and friends and in community
10:39
We began to think of this as a kind of fitness, a social fitness
10:44
ogous to physical fitness. So the question comes up, how do I know how I'm doing
10:50
Am I socially fit? Check in with yourself and say, do I have the kinds of relationships that I would like
10:59
Do I have as many relationships as I would like? And if it doesn't feel like the right amount
11:04
there are things you can do to make things the way you would like them to be
11:10
Each of us can do that through small actions that we repeat over and over again reaching out to friends to family through little texts or emails or phone calls Making sure that we see people in person
11:26
who we want to keep in our lives. Paying attention to how often we're seeing people
11:32
how often we're in touch with people. Pay off into social networks that are vibrant
11:38
and make us happier and keep us healthier. One way to map your social universe is to think of it as four quadrants, that on the
11:54
horizontal axis, it's how frequently do I see this person from infrequently to frequently
12:01
And on the vertical axis, it could be how energizing is this relationship
12:08
Up at the top, it could be very energizing. Down at the bottom, it could be depleting
12:13
and then see where each important person in your life fits on this grid
12:20
You might find that there are some people you see frequently who are quite depleting, who drain your energy
12:27
You might see that there are other people who you don't see very often
12:31
but are so energizing when you're with them. And that can give you some pointers in terms of changes
12:37
you might like to make in your relationships. A lot depends on what you see in that little diagram that you make and then what you want to do about it
12:50
We're all on a continuum from shyness to extroversion. Shy people may need just a few others in their life
13:00
And actually, shy people get a lot of their energy from solitude, from alone time
13:06
whereas extroverts get their energy from people and they may want a lot of people in their lives
13:13
And so each of us needs to check in with ourselves. What's right for me
13:19
And to really work on our social world based on what we know works for us
13:26
whether it's a lot of people or a small number of people or something in between
13:36
When we watch these thousands of lives play out over time, what we see is that the good life is an ongoing process
13:46
And it's a process of continual change, which is different from what we all wish for
13:52
which is that we would finally get to a place where everything's good and it's going to stay that way
13:57
That's not the truth of anybody's life. The good life involves a practice of ongoing care for each other
14:06
for our relationships, care for ourselves, and weathering all the unexpected challenges
14:13
that come along day after day, week after week. My hope for what people will take away from these ideas
14:22
is the truth that if you're not happy all the time, that doesn't mean you're doing something wrong
14:29
That we can sometimes imagine that other people have it all figured out
14:33
and we're the only one who has ups and downs in our life. Let me tell you from having studied thousands of people
14:39
over eight decades that everybody has ups and downs. We never figure it out ultimately
14:46
and that that's perfectly normal and actually it's what makes life rich and interesting
