Smiling too much at work can seriously damage your health, German scientists have claimed.
Researchers at a university in Germany – where the right to be surly is almost a national pastime – now claim enforced jolliness on the job is much more likely to make people fall ill.

This in turn can trigger more serious ailments, such as high blood pressure and other cardiovascular problems, he claimed.
“Every time a person is forced to repress his true feelings, there are negative consequences for his health,” Zapf added.
