COPENHAGEN, Denmark, Nov. 18 (UPI) -- For a man who is unfit, high physical demands at work are linked to an increased risk of death from heart disease, researchers in Denmark say.
Study leader Andreas Holtermann of Bispebjerg University Hospital in Copenhagen and colleagues analyzed 2,707 men. Thirty percent of men in this group had high physical work demands, compared to 3.5 percent for those at higher socioeconomic levels, Holtermann said.
