survey by the National Sleep Foundation revealed that Americans think they’re sleeping, on average, somewhere around seven hours a night. The American Time Use Survey, which has people actually measure their sleep, corrected this number to 8.6 hours. Another study found that people who claimed to work sixty to sixty-four hours per week were actually averaging more like forty-four hours per week, while those claiming to work more than seventy-five hours were actually working less than fifty-five.
