There are many things known that cause heart attacks, stress, diabetes, smoking…we can now add unemployment. At some point in your life, if you were unemployed, whether you quit, were fired or were laid off, you may have increased your chances of getting a heart attack. A study done at Duke University shows unemployment in your lifetime will start affecting your chances of a heart attack after the age of 50. They believe the greatest risk comes from involuntary job loss like being fired or laid off.  One good thing is ‘retirement’ doesn’t seem to possess the same risks.
