Why Do Nuns Live Longer?
In the 1930s, Dr. Keltner asked a group of about 100 nuns to write essays on why they took their novicious lifestyle. The crucial variable he found was those nuns as novices who used positive emotion words like I'm eager to serve Jesus lived for 15 years longer than ones who were just deadpan. Today's literature has since become much more refined and indeed optimistic people, people with high positive emotion, live between six and eight years longer than pessimists.
