People smile for so many different reasons don't they? Well, they smile for reasons like to forget their worries, tell someone they are fine; etc etc. But it all involves one thing- sharing happiness and joy. Its as is smiles are the different shades of the same color. There is a purpose behind every smile but its not necessary that each smile shiuld have a reason. The scientists say that there are 19 types of smiles but who count (other than them of course..) ? And then the fact that everyone in this worls smiled today atleast once makes me realize that a smile is the only thing that is priceless and free of cost! A smile can lift a ton of weight from someones heart. Sometimes people smile to intidimate or even scare others which is truly hilarious. But, smile is a treasure that is omnipresent. We share, give or take smiles instinctively most of the time. It is more priceless than any treasure. They say that if you kept smiling then you would live ten times longer. Maybe...just maybe..if someone never smiled at all then they would die at the age of twenty. Even a baby can smile so let us not be lazy or scared and smile cheerfully to light up the world with happiness.
