Feeling purposeless in your 60s or 70s isn’t simply a failure of character. Researchers can measure a broad decline in purpose across later adulthood, and some of its strongest correlates are exactly the losses that accumulate with age — declining health, widowhood and the disappearance of long-held social roles.
Longitudinal research finds an average decline in later-life purpose, but health, bereavement, social roles and even the questionnaire used all complicate the story.
