What's the key to living longer? While eating your broccoli and running probably play a role, so might self-perceived age. People who feel younger than their actual age have reduced mortality, according to a research letter in JAMA.
U.K. researchers analyzed data from some 6500 adults aged 52 years and older who were asked, "How old do you feel you are?" Almost 70% of participants reported feeling at least 3 years younger than their actual age, 25% felt close to their actual age, and 5% felt more than a year older than their true age.
During approximately 8 years' follow-up, mortality was lower in participants who felt younger (14%) than in those who felt their actual age (19%) or older (25%). After adjustment for covariates (e.g., age, ethnicity, sex), feeling older than chronological age was a significant independent predictor of mortality. A relationship existed between self-perceived age and cardiovascular death but not cancer death.
