Optimists live longer

Here’s a good reason to turn that frown upside down: Optimistic people live as much as 15% longer than pessimists, according to a new study spanning thousands of people and 3 decades.  After controlling for health conditions, behaviors like diet and exercise, and other demographic information, the scientists were able to show that the most optimistic women (top 25%) lived an average of 14.9% longer than their more pessimistic peers. For the men the results were a bit less dramatic: The most optimistic of the bunch lived 10.9% longer than their peers, on average, the team reports today in the Proceedings of the National Academy of Sciences.
