People with higher optimism more likely to live 'exceptionally long lives'
New research finds that individuals with higher optimism tend to live longer and also have greater odds of living 85 years and more.

Optimism may boost longevity, new research finds.
A recent PNAS paper describes how the researchers assessed the link between higher optimism and longer lifespan, with a particular focus on the chances of reaching "exceptional longevity."
The team carried out the study because most research on exceptional longevity has tended to focus on the effect of "biomedical factors."
More recently, however, scientists have become interested in the role of nonbiological factors.
"While research has identified many risk factors for diseases and premature death," says first and corresponding author Lewina O. Lee, Ph.D., assistant professor of psychiatry at Boston University School of Medicine, "we know relatively less about positive psychosocial factors that can promote healthy aging."
She and her colleagues defined optimism as the "general expectation that good things will happen or the belief that the future will be favorable because one can control important outcomes."
They suggest that because it may be possible to alter optimism using relatively straightforward therapeutic techniques, their findings have strong implications for public health.
"Our study contributes to scientific knowledge on health assets that may protect against mortality risk and promote resilient aging," Lee adds.
What the study found
For the analysis, the team brought together data on 69,744 females in the Nurses' Health Study (NHS) and 1,429 males in the Veterans Affairs Normative Aging Study (NAS).
The NHS data covered 10 years of follow-up between 2004 and 2014, while the NAS data included 30 years of follow-up between 1986 and 2016.
As a routine part of both projects, all participants completed regular health surveys that included questions about diet, alcohol intake, smoking, and other health-related behaviors.
