Adults who can laugh at life's ups and downs may live longer than those who have trouble cracking a smile, concludes a Norwegian study of about 54,000 people tracked for seven years.
At the start of the study, participants filled out questionnaires on how easily they found humor in everyday life and how important they felt it was to have a humorous perspective, USA Today reported.
People who scored in the highest 25% of humor appreciation were 35% more likely to be alive at the end of seven years than those in the bottom quarter, the study found.
The survival advantage of having a humorous outlook was especially noticeable in a subgroup of 2,015 cancer patients. Those with a healthy sense of humor were about 70%less likely to die than those with a weak sense of humor, USA Today reported.
The study was presented at a meeting of the American Psychosomatic Society.
