Is there anyone who can resist a smile after
looking at the above picture?!
Smiling is contagious; when one person smiles,
it changes the moods of other people and makes
things happier. Studies have shown that smiling
releases endorphins which are natural pain killers.
But like all other things in life, a smile should be
natural. A forced smile is artificial and has no effect.
Natural smile comes from the heart and touches the
hearts of other people.
