NAUTILUS.- In 1979, psychologist Ellen Langer and her students carefully refurbished an old monastery in Peterborough, New Hampshire, to resemble a place that would have existed two decades earlier. They invited a group of elderly men in their late 70s and early 80s to spend a week with them and live as they did in 1959, “a time when an IBM computer filled a whole room and panty hose had just been introduced to U.S. women,” Langer wrote. Her idea was to return the men, at least in their minds, to a time when they were younger and healthier—and to see if it had physiological consequences.Más...
Every day Langer and her students met with the men to discuss “current” events. They talked about the first United States satellite launch, Fidel Castro entering Havana after his march across Cuba, and the Baltimore Colts winning the NFL championship game. They discussed “current” books: Ian Fleming’s Goldfinger and Leon Uris’ Exodus. They watched Ed Sullivan and Jack Benny and Jackie Gleason on a black-and-white TV, listened to Nat King Cole on the radio, and saw Marilyn Monroe in Some Like It Hot. Everything was transporting the men back to 1959.
When Langer studied the men after a week of such sensory and mindful immersion in the past, she found that their memory, vision, hearing, and even physical strength had improved. She compared the traits to those of a control group of men, who had also spent a week in a retreat. The control group, however, had been told the experiment was about reminiscing. They were not told to live as if it were 1959. The first group, in a very objective sense, seemed younger. The team took photographs of the men before and after the experiment, and people who knew nothing about the study said the men looke
d younger in the after-pictures, says Langer, who today is a professor of psychology at Harvard University.
Langer’s experiment was a tantalizing demonstration that our chronological age based on our birthdate is a misleading indicator of aging. Langer, of course, was tackling the role of the mind in how old we feel and act. Since her study, others have taken a more objective look at the aging body. The goal is to determine an individual’s “biological age,” a term that aims to capture the body’s physiological development and decline with time, and predict, with reasonable accuracy, the risks of disease and death. As scientists have worked to pinpoint a person’s biological age, they have learned that organs and tissues often age differently, making it difficult to reduce biological age to a single number. They have also made a discovery that echoes Langer’s work. How old we feel—our subjective age—can influence how we age. Where age is concerned, the pages torn off a calendar do not tell the whole story.
