Smiling, anger and clumsiness etc. Why do those expressions change our facial expression often? Are they due to changes in our body? These expressions are like changing colors of a flower, on our face.
These facial expressions are a projection of our inner attitudes or states of mind. They are just a medium, through which we show others what we are thinking of or what we feel.
Mostly people read each other’s mind through their facial expression. So like a book in which we put our thoughts in words, so are our facial expressions.
Biologically, if we keep a habit of smiling it will keep our face looking young. The more we feel stress depression or other negative emotions, the more wrinkles will appear on our face.
In conclusion, as facial expressions are a medium of our attitudes, keeping a cute smile on our face is ethically and biologically important for our happiness and health as well.
