Kindness is the act or the state of being kind, being marked by good and charitable behavior, pleasant disposition, and concern for others. It is known as a virtue, and recognized as a value in many cultures and religions.
Research has shown that acts of kindness does not only benefit receivers of the kind act, but also the giver, as a result of the release of neurotransmitters responsible for feelings of contentment and relaxation when such acts are committed. (With material from: Wikipedia)
