1) John Bishop, 31, is an investment banker who works for Citigroup's global energy team in New York. A recent workday for Bishop consisted of heading to the office for a conference call at 6:00 pm. He left the office at 1:30 am and had to be on a plane that same morning for a 9:00 am presentation in Houston. Following the presentation, Bishop returned to New York the same day, and by 7 pm he was back in the office to work an additional three hours. Says Bishop \"I might be a little skewed to a workaholic, but realistically, expecting 90 to 100 hours a week is not unusual\". 2) Irene Tse, 34, heads the government bond-trading division at Goldman Sachs. For ten years, she has seen the stock market go from all-time high to recession levels. Such fluctuations can mean millions of dollars in either profits or losses. \"There are days when you can make a lot, and other days when you lose so much you are just stunned by what you've done\
