Good morning. I’m going to start my lecture with some questions. 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?
     (23)There was a recent survey asking young adults 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. 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.(24)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.
    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.(25)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 happier, and they live longer than people who are less well connected. 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. 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.
    I’d like to close with just one sentence: The good life is built with good relationships. Thank you.
