How to Stop Boredom from Killing You and Your Career

A study of civil servants conducted by researchers from the Department of Epidemiology and Public Health, University College, London, found that "those who had high levels of boredom were 37 percent more likely to be dead from any cause, including heart disease, at the end of the study than those who were not bored."

It's not the actual boredom that killed them, but that they were more likely to indulge in unhealthy habits like drinking, drugs and smoking as an escape.
