Interestingly, one of its core postulates is that the essential sociality of us all, or the universal human impulse to relate to others. In so far as we are relationship-seeking beings, then, what is the connective tissue that actually binds people together, that gives effect to this relational striving? In contrast to the popular belief that knowledge precedes action, I argue that emotions are what prompt and sustain human interactions - and not emotions in the conventional sense, of private feeling states stored inside our heads, each with its own unique biochemical correlate. I regard emotions, instead, as intersubjective phenomena that can be said to exist between people. How else does one explain being moved by a piece of music, a spellbinding movie or a superb novel, if not that some mysterious element - an emotion - has connected to the heart of the composer, the director or the author to the heart of the listener, the watcher or the reader?

All of these studies, as well as our own Harvard Study, bear witness to the importance of human connections. They show that people who are more connected to family, to friends, and to community, are happier and physically healthier than people who are less well connected. People who are more isolated than they want to be find their health declining sooner than people who feel connected to others. Lonely people also live shorter lives. Sadly, this sense of disconnection from others is growing across the world. About one in four Americans report feeling lonely—more than sixty million people. In China, loneliness among older adults has markedly increased in recent years, and Great Britain has appointed a minister of loneliness to address what has become a major public health challenge.

Many difficulties in relationships stem from old habits. We develop automatic, reflexive behaviors over the course of our lives that become so intimately woven into our days that we don’t even see them. In some cases, we become used to avoiding certain feelings and turning away, while in other cases we might be so overcome by emotion that we act on our feelings before we realize it.

The complex emotional lattice of every family is unique in important ways, and our families affect us in ways that other relationships do not. Families share history, experience, and blood as no other relationships can. We can’t replace a person we’ve known for our entire lives. More importantly, we can’t replace a person who’s known us for our entire lives. Nurturing and enriching these relationships despite challenges, persevering, and appreciating the positive things we get from them is worth the trouble. Bob thinks of a moment when, as a young man, he was going through a time in which he was incredibly angry at his parents, and an uncle took him aside. I know you’re mad, his uncle said. But just remember: nobody is ever going to care about you this much ever again.

Our brains, tuned for novelty and danger, catch fire when stimulated by the wonders of new technology and the stresses of the workplace. Compared to those two things, the subtle currents of our positive relationships, so important to our well-being, are likely to be overshadowed. If our relationships—both at work and at home—are going to thrive in this new work environment, we have to elevate and care for them. We are the only ones who can. If we don’t, and if the Harvard Study still exists in eighty years, then when today’s youngest generation reaches their 80s and the interviewers ask if there was anything they regret about their lives, they might look back, as some of our First Generation participants did in their comments quoted earlier in this chapter, and realize that something crucial has been lost.
