what keeps us healthy and happy as we go through life if you were going to invest now in your future best self where would you put your time and your energy there was a recent survey of millennials asking them what their most important life goals were and over 80 percent said that a major life goal for them was to get rich and another 50 percent 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 that 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 hindsight is anything but 2020. 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 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 the first group started in the study when they were sophomores at harvard college they all finished college during world war ii and then most went off to serve in the war and the second group that we've 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 the 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 we interviewed their parents and then these teenagers grew up into adults who entered all walks of life they became factory workers and lawyers and bricklayers 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 asked that question [Laughter] 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 it turns out that people who are more socially connected to family to friends to community are happier they're physically healthier and they live longer than people who are less well connected and the experience 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 mid-life 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're 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 you have and it's not 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 worse 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 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 and when we gathered together
everything we knew about them at age 50 it wasn't their middle-aged 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 80s that on the days when they had more physical pain their moods stayed just as happy but the people who
were in unhappy relationships on the days when they reported more physical pain it was magnified by more emotional pain and the third big lesson that we learned about relationships on 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 where they really feel they can count on the other person in times of need those people's memories stay sharper longer and the people in relationships where they feel
they really can't 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 felt that they could really 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 well-being this is wisdom that's as old as the hills why is this so
hard to get and so easy to ignore well we're human what we'd really like is a quick fix something we can get that'll make our lives good and keep them that way relationships are messy and they're complicated and the hard work of tending to family and friends that's not sexy or glamorous it's also lifelong 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 fared the best were the people who leaned into relationships with family with friends with community so what about you let's say you're 25 or you're 40 or you're 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 who you haven't spoken to in years because those all too common family feuds take a terrible toll on the 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 heart burnings 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 [Applause] you
