only a minute and a half.
By design, the Treadmill Test was exhausting. Not just physically but mentally. By measuring and then adjusting for baseline physical fitness, the researchers designed the Treadmill Test to gauge âstaminaandstrength of will.â In particular, Harvard researchers knew that running hard was not just a function of aerobic capacity and muscle strength but also the extent to which âa subject is willing to push himself or has a tendency to quit before the punishmentbecomes too severe.â
Decades later, a psychiatrist named George Vaillant followed up on the young men in the original Treadmill Test. Then in their sixties, these men had been contacted by researchers every two years since graduating from college, and for each there was a corresponding file folder at Harvard literally bursting with questionnaires, correspondence, and notes from in-depth interviews. For instance, researchers noted for each man his income, career advancement, sick days, social activities, self-reported satisfaction with work and marriage, visits to psychiatrists, and use of mood-altering drugs like tranquilizers. All this information went into composite estimates of the menâs overall psychological adjustment in adulthood.
It turns out that run time in the Treadmill Test at age twenty was a surprisingly reliable predictor of psychological adjustment throughout adulthood. George and his team considered that staying on the treadmill was also a function of how physically fit these men were in their youth, and that this finding merely indicated that physical health predicted later psychological well-being. However, they found that adjusting for baseline physical fitness âhad little effect on the correlation of running timewith mental health.â
In other words, Will Smith is on to something. When it comes to how we fare in the marathon of life, effort counts tremendously.
âHow long would you have stayed on the treadmill?â I asked George recently. I wanted to know because, in my eyes, George is himself a paragon of grit. Early in his career, not long after completing his residency in psychiatry, George discovered the treadmill data, along with all the other information on the men collected to that point. Like abaton, the study had been handed from one research team to another, with dwindling interest and energy. Until it got to him.
George revived the study. He reestablished contact with the men by mail and phone and, in addition, interviewed each in person, traveling to all corners of the world to do so. Now in his eighties, George has outlived most of the men in the original study. He is currently writing his fourth book on what is by now the longest continuous study of human development ever undertaken.
In answer to my question about his own treadmill perseverance, George replied, âOh,Iâm not all that persistent. When I do crossword puzzles on the airplane, I always look at the answers when I am a little bit frustrated.â
So, not very gritty when it comes to crossword puzzles.
âAnd when something is broken in the house, I turn it over to my wife, and she fixes it.â
âSo you donât think youâre gritty?â I asked.
âThe reason why the Harvard study works is that I have been doing it constantly and persistently. Itâs the one ball Iâve kept my eye on. Because Iâm totally fascinated by it. There is nothing more interesting than watching people grow.â
And then, after a short pause, George recalled his days at prep school, where, as a varsity track athlete, he competed in pole vaulting. To improve, he and the other vaulters did pull-ups, which he calls âchins,â because you start by hanging off a bar and then pull yourself up to where your chin hovers just above, then you drop down again, and repeat.
âI could do more chins than anyone. And it wasnât because I was very athleticâI wasnât. The reason
