A purpose-driven life may last longer

Study shows an association between a strong sense of purpose in life and a lower risk of death from cardiovascular problems and blood conditions.

If you believe your life has meaning, it could potentially be longer, says a new study published online May 24 by JAMA Network Open.

Study authors found that among a group of nearly 7,000 adults over age 50, those who scored highest on a scale that measured "life purpose" were less likely to die during the study period, and also less likely to die during the same period from heart, circulatory, or blood conditions, compared with those who scored lower.
