“A Boston study published this month suggests people who tend to be optimistic are likelier than others to live to be 85 years old or more,” reports NPR:
That finding was independent of other factors thought to influence life’s length — such as “socioeconomic status, health conditions, depression, social integration, and health behaviors,” the researchers from Boston University School of Medicine and the Harvard T.H. Chan School of Public Health say… The study included 69,744 women and 1,429 men. Both groups completed survey measures to assess their level of optimism, as well as their overall health and health habits such as diet, smoking and alcohol use.
In the survey, study participants were asked if they agreed with statements such as “in uncertain times I usually expect the best” or “I usually expect to succeed in things that I do.” Health outcomes from women in the study were tracked for 10 years, while the men’s health was followed for 30 years. Researchers found that the most optimistic men and women demonstrated, on average, an 11-15% longer lifespan, and had far greater odds of reaching 85 years old, compared to the least optimistic group.
