If you feel depressed or if somebody didn't do something orderly that made you frown, it is recommended that you turn that frown upside down. Even if you don't feel like smiling, try to. It was scientifically proved by psychologists from the University of Kansas that fake smiles have the equivalent effect of naturally smiling. The psychologists stated that smiling is a moving of a muscle that can be triggured by emotional and psycological feelings. If you smile a fake smile, it will still send that emotion to your brain making you happier.

Another reason you should smile is that smiling can influence others to smile as well. According to neuroscientist, we all posses something called mirror neurons which are cells in the brain that are activated when we perform a given action as well as when we witness someone else performing it. So when a person smiles, mirror neurons respond to the acts of both seeing and doing making us smile with them.

Smiling can be beneficial to your health and can benefit other people as well by smiling with them. We can realize that smiling is a new virus that is more contagious than the MERS virus and a lot more healthier than it.
