Smiles are innate behaviour and it is of human nature to express it when sensations are perceived, let’s take for example, new born babies smile for no reason because they’re naturally born with it.
Smile is a facial expression that expresses feelings, such as, happiness, satisfaction, joy, etc.
In some cases, people don’t really smile because they’re happy, they smile as a result of psychological defence to cover up insecurity, doubt, frustration, nervosity and dominance over others.
Researcher say smiles helps increase self confidence and helps win over glumly mood and i believe smile is a tool for over coming anger, forgiven, favour and you can simply brighten up someones day with a simple smile, generally I think people should learn how to give it out more freely.
“Beauty is power; a smile is its sword. Let my soul smile through my heart and my heart smile through my eyes, that I may scatter rich smiles in sad hearts. We shall never know all the good that a simple smile can do. The greatest self is a peaceful smile, that always sees the world smiling back”.
