Live Longer by Changing Your Name:  People with "positive" initials—ones that spell out things like J.O.Y. or W.O.W. live nearly 4-1/2 years longer than people with neutral initials, according to a University of California, San Diego study. D.U.D.'s live nearly three years less. Other initials that may shorten life: I.L.L. and D.E.D.
