No matter what language barriers stand in between us, a smile is a universal sign of happiness and dependability in regards to non-verbal interaction.

According to a study performed in 2005, you might nearly say that receiving an authentic, wholehearted smile from someone is more beneficial than getting cash. In the words of Dr. David Lewis, the psychologist who examined these findings: “The powerful emotions triggered when someone important in our lives smiles at us and we smile back changes our brain chemistry. It creates what is termed a ‘halo’ effect that helps us remember other happy events more vividly, feel more optimistic, more positive, and more motivated.”
