Plastic surgeon Michael Kulick poses for a portrait at his practice in San Francisco, California July 31, 2015. Kulick now spends about 16 hours a week doing tummy tucks and other surgical procedures, double what he did in 2008. Janet Yellen made her reputation as an early spotter of the looming slump seven years ago when she highlighted some unorthodox indicators of decline in consumer spending: tummy tucks, gourmet dining and country club memberships. Now she is Federal Reserve Chair, Yellen will find a much brighter picture from her novel monitoring system as she and the Fed board mull the first U.S. interest rate hike for nine years, which could come as early as September.
