If you live life with a positive outlook you may have a better shot at surviving heart disease.

Researchers from Duke University followed more than 2,800 patients with heart problems. What they found is that the optimists were half as likely to die over the course of the study.

Experts have many theories about why optimism may contribute to heart health. Positive thinkers tend to take better care of themselves. They are also more likely to take their medications and to follow doctors' orders about exercising and eating healthy.

Another possibility is that pessimists have more stress which can cause inflammation in the bloodstream and increase heart risk.
