A new study out of the U.K. has some bad news for overachievers: Working 10-11 hours a day on a regular basis can increase your risk of heart disease by close to two-thirds. Out of a group of 6,000 civil servants, the study found 369 cases “where people suffered heart disease that caused death, had a heart attack or developed angina.”
A worker at a McDonald’s branch in Japan died of “karoshi” — the Japanese term for death from overwork — according to officials at the local government labor bureau. The employee, a 41-year-old woman, had put in about 80 hours a month in overtime for six months before she died. “We determined her work caused the illness,” said an official at the agency.
