A happy heart may be the best prescription for a healthier life.

Scientists have long known that people who are chronically angry, anxious or depressed have a higher risk of heart attacks. Now, a Harvard review of the flip side of that psychology concludes that being upbeat and optimistic just may help protect against heart disease.

A review of dozens of studies finds optimistic people had half the risk of first heart attack.

Why is that?

Previous research shows the stress associated with negative traits can lead to damage of arteries and the heart itself.
