In a 2015 study, people who felt their life had deep meaning, purpose and value were 3x as likely to live longer. In an analysis of the English Longitudinal Study of Aging, it was associated with increased survival. 29·3% of people in the lowest wellbeing quartile died during the average follow-up period of 8·5 years compared with 9·3% of those in the highest quartile.
Associations were independent of age, sex, demographic factors, and baseline mental and physical health. This suggests that a eudemonic sense of wellbeing may have a protective role in health maintenance.
