happiness vs. heart disease

found this interesting article on the web and thought i would share it with you.
study shows that happiness helps to ward off heart disease. over 1700 people were analyzed in the study and asked to rate their happiness level. during the 10 year span, 145 of the ones who rated high for depression and stress were diagnosed with heart disease.
though it cannot be absolutely proven that being happy will prevent heart disease, it will allow you a better life.
so like the song says "don't worry, be happy"
