A surprising predictor of how long you’ll live isn’t a lab value at all. It’s whether your life feels like it’s going somewhere.

What the research links

In a study of more than 6,000 U.S. adults over 50, people who reported a stronger sense of purpose were meaningfully less likely to die over the following years — a link that held even after accounting for other measures of wellbeing (Alimujiang et al., JAMA Network Open, 2019). A separate analysis found the connection between purpose and longer life showed up across every stage of adulthood, young and old alike (Hill & Turiano, Psychological Science, 2014).
