TEMPE, AZ—Lillian Reselman celebrated her 91st birthday Monday by continuing to do what she's been doing for more than nine decades: outliving those closest to her. "This amazing lady has outlived not only two sisters, a brother, and a husband, but scores of friends—and even her only son, who died in the Vietnam War," Oak Hill nursing-home employee Tanya Stoles said. "Lily is a real survivor." Stoles credited Reselman's incredible longevity to her "great endurance."
