New research published in Social Science & Medicine has shown that your short fuse might actually be an indicator of a short life span.

Researchers from Iowa State University used data from a nationally representative sample of 1,307 male heads of the household, all of whom had been followed from 1968 to 2007. Between 1968 and 1972, the men were questioned on a yearly basis about their anger levels. Each of their scores from those five years were then averaged. What researchers found: men with admittedly shorter fuses at around 35 years old were more likely to be dead 35 years later than those with easier tempers. The angriest 25 percent had a 1.57-fold increase in their risk of dying early, compared to the calmest 25 percent.

Why? Anger is a form of stress and stress increases cortisol levels in the bloodstream. Previous studies have linked manifestations of stress with a variety of negative physiological processes, such as atherosclerosis—or clogged arteries, which can lead to heart attacks; IBS (Irritable Bowel Syndrome); increased strokes and other cardiac problems. So, perk up, guys, if you want to live to witness all the things that will piss you off years from now—and the good, of course.
