Happiness is a state of mind that prolongs your life. The more you smile, the more you will live.
Smiling sends a signal to the brain and your mood is up. All of a sudden you have loads of energy. This works both ways – whether you smiled first or you thought you were happy first. Either way, the brain recognizes that event and starts the release of the happy hormones.

A happy child, or a happy cat, a colorful butterfly, or the sun are all concepts that make us smile.
