Another proof to stay true!

A German scientist has proved that smiling while repressing ones true feelings can harm your health.

Dieter Zapf of the Johann Wolfgang Goethe University in Frankfurt, Germany studied 4,000 volunteers working in a fake call center. Half were allowed to respond in kind to abuse on the other end of the line while the other half had to repress their true feelings and were not allowed to respond in kind to abusive callers.


He found that those able to answer back had a brief increase in heart rate. Those who could not had stress symptoms that lasted much longer.
"Every time a person is forced to repress his true feelings there are negative consequences," Zapf said. "We are all able to rein in our emotions but it becomes difficult to do this over a protracted period."
