Recently in India, food outlet KFC allowed people to pay just smiling. In other countries, smiling schools have been training youngsters to smile more than they do these days. If you think all the above is laughable, first laugh a bit. Then take a stock of your surroundings. How many people around you are smiling right now? It doesn’t matter where you are,work,home or commuting…..or better still when were you last smiling?
