Something was wrong with Peter. Eilene Zimmerman noticed that her ex-husband looked thin, seemed distracted, and was frequently absent from activities with their children. She thought he looked sick and needed to see a doctor, and indeed, he told her he had been diagnosed with an autoimmune disorder. Yet in many ways, Peter also seemed to have it all: a beautiful house by the beach purchased after their divorce, expensive cars, and other luxuries that came with an affluent life. Eilene assumed his odd behavior was due to stress and overwork–he was a senior partner at a prominent law firm and had been working more than 60 hours a week for the last 20 years.
