Naomi West of Bridgewater, Va., and Erika Bergmann of York, Pa., participate in an exercise Thursday morning as instructed by Gayle Appel Doll, the main session's keynote speaker. NOACers were asked to stare at each other for one minute, looking each other over. They then turned their backs on each other and changed five aspects of their appearance during a second minute. Lastly, they turned around and tried to identify what had changed on each other.
