"Wear a smile and you have friends; wear a scowl and you have wrinkles."

The study results fit with a large body of psychological research that has long shown that the mere act of smiling makes people feel better. Frowns make them feel worse.
"I went back and read Charles Darwin. Back in the 1870s, he brought up that you sort of are the emotions you express on your face," Finzi says.
The facial muscles feed information to the emotion centers of the brain, which in turn respond with chemicals that produce happy or sad feelings. The loop is complete when those feelings are sent back to the brain, reinforcing expressions on the face. Scientists have proven, however, that facial expressions can alter heart rate, skin temperature and blood volume.
Another theory linking facial expression and mood involves a different sort of loop – a social feedback loop, illustrated and immortalized in the saying "Laugh and the world laughs with you. Weep and you weep alone." In psychological circles, it's called the facial feedback hypothesis.
