Think about it.

My manager mentioned today that the world would be cured of all its problems if all women smiled.

yes. you read that correctly.

He continues to tell me that people in the middle east are so miserable because the women cover their faces.
Also mentioned was that if a woman smiled at the man that was just about to commit suicide or rob a bank or start a war then that man would not kill himself or rob that bank or start that war. The world would be a happier more blissful place.

What do you think?

A generous heart, kind speech, and a life of service and compassion
are the things which renew humanity.
-Buddha
