Happiness: Squeezing the Lemon
The Atlantic looks at a long term study into the nature of happiness. Run over 70 years and led by George Vaillant, the study offers profound insight into the human condition as well as the man himself.
The formulaic conclusions of Valliant are straightforward:
What allows people to work, and love, as they grow old? By the time the Grant Study men had entered retirement, Vaillant, who had then been following them for a quarter century, had identified seven major factors that predict healthy aging, both physically and psychologically.
Employing mature adaptations was one. The others were education, stable marriage, not smoking, not abusing alcohol, some exercise, and healthy weight. Of the 106 Harvard men who had five or six of these factors in their favor at age 50, half ended up at 80 as what Vaillant called â€œhappy-wellâ€ and only 7.5 percent as â€œsad-sick.â€ Meanwhile, of the men who had three or fewer of the health factors at age 50, none ended up â€œhappy-wellâ€ at 80. Even if they had been in adequate physical shape at 50, the men who had three or fewer protective factors were three times as likely to be dead at 80 as those with four or more factors.
What factors donâ€™t matter? Vaillant identified some surprises. Cholesterol levels at age 50 have nothing to do with health in old age. While social ease correlates highly with good psychosocial adjustment in college and early adulthood, its significance diminishes over time. The predictive importance of childhood temperament also diminishes over time: shy, anxious kids tend to do poorly in young adulthood, but by age 70, are just as likely as the outgoing kids to be â€œhappy-well.â€ Vaillant sums up: â€œIf you follow lives long enough, the risk factors for healthy life adjustment change. There is an age to watch your cholesterol and an age to ignore it.â€
The study has yielded some additional subtle surprises. Regular exercise in college predicted late-life mental health better than it did physical health. And depression turned out to be a major drain on physical health: of the men who were diagnosed with depression by age 50, more than 70 percent had died or were chronically ill by 63. More broadly, pessimists seemed to suffer physically in comparison with optimists, perhaps because theyâ€™re less likely to connect with others or care for themselves.
However more touching and much more profound are his insights into the struggle to live a life:

Only with patience and tenderness might a person surrender his barbed armor for a softer shield. Perhaps in this, I thought, lies the key to the good lifeâ€”not rules to follow, nor problems to avoid, but an engaged humility, an earnest acceptance of lifeâ€™s pains and promises. In his efforts to manifest this spirit, George Vaillant is, if not a model, then certainly a practiced guide. For all his love of science and its conclusions, he returns to stories and their questions. When I asked him if there was a death that had affected him, he mentioned Case No. 47â€”â€œAlan Poeâ€â€”an inspiring, tragic man, who left many lessons and many mysteries, who earnestly sought to â€œsqueeze that lemon.â€
