A positive attitude makes you less likely to have a heart attack, a new study suggests.

Researchers at John Hopkins University studied nearly 1,500 healthy siblings of people who suffered heart events before the age of 60.

They found that those who reported feeling happy and satisfied with life were 30 percent less likely to have a heart attack.

Additionally, people with a cheerful outlook who had the highest risk for a heart event had a 50 percent reduced risk of having a heart event. The study took into account other heart disease risk factors including age, smoking, diabetes, high cholesterol levels and high blood pressure.
