DIED. CHRISTY HENRICH, 22, former gymnast; of multiple-organ failure stemming from anorexia nervosa; in Kansas City. In 1988 Henrich missed immortality by 0.118 points--the all but immeasurable gap between the young gymnast's performance and a berth on the 1988 U.S. Olympic team. Henrich, who started training at age four, was a competitor so obsessive that she was nicknamed E.T.--Extra Tough. But she suffered from a secret obsession as well: the compulsive conviction that she was always too fat. Henrich's anorexia grew so severe that by 1991 she was too weak to compete. At her death, she weighed 60 lbs.
