Leader Longevity

Queen Elizabeth turned 95 this week. Her husband, Prince Philip, recently died just shy of his 100th birthday. Former US vice president Walter Mondale died this week at the age of 93, and Jimmy Carter is still alive and kicking at 96. Are you seeing a pattern? S. Jay Olshansky, professor of biostatics and public health at the University of Illinois at Chicago, explains some of our leaders are living longer than the general population.
