According to a new study out of University College London, working 11 hours or more on a daily basis will KILL YOU.

They found that people who work that many hours have a 67% higher risk for developing coronary heart disease than people who work seven or eight hours.

There was such a high connection between long work hours and heart disease that the researchers believe it's on the same level as other more common predictors like cholesterol levels, blood pressure, and smoking.
