In an article which appeared in The Wall Street Journal, Melinda Beck referred to a growing body of research which shows that feeling grateful for the good things that happen to us can greatly improve our psychological, emotional and physical health.  According to Ms. Beck, “Adults who frequently feel grateful have more energy, more optimism, more social connections and more happiness than those who do not.”  She goes on to say that grateful people are less likely to be depressed, envious or greedy.   In addition, they earn more money, sleep more soundly and have a greater resistance to viral infections.  This must be why the ancient Greeks and Romans referred to gratitude as an “indispensable human virtue.” With a payoff this huge, none of us can’t afford not to be grateful.
