Smiles are contagious. It's no myth... it's biology.
Scientists have shown that seeing a smile triggers an automatic response in our brains which causes us to smile, too (a phenomenon known as "facial feedback"). This response in turn creates positive emotions.
—"Facial Efference and the Experience of Emotion," by P.K. Adelman and R.B. Zajonc (1989).
