Dean Graziosi discusses how smiling — even when forced — influences internal neurochemistry (releasing dopamine, serotonin, endorphins) and external perception. He cites studies (a UC Berkeley college yearbook study and a study of smiling baseball rookies) and shares personal anecdotes (his daughter noticing he hadn't smiled) to argue that outer appearance, particularly smiling, shapes mental state, health, relationships, and perceived success.
