"A new study [1] by the two groups says that working 55 or more hours a week is a “serious health hazard.” It estimates that long working hours led to 745,000 deaths worldwide in 2016, a 29 percent increase over 2000. Men accounted for 72 percent of the fatalities; the worst concentrations were in the Western Pacific and Southeast Asia, and particularly among 60- to 79-year-olds who had worked long hours after the age of 45."
