According to a new study, guys with physically demanding jobs are 18 percent more likely to suffer a premature death than guys who sit behind desks.
These results were sort of surprising because we've been hearing for years about how bad it is for us to be sedentary.
But the researchers think that the problem is all about the grind.
Getting some exercise by going for a jog or lifting some weights is a good thing because it stresses the body -- and then lets the body recover.
In jobs where physical activity is nonstop for eight hours straight, the body takes a beating -- and never gets a chance to bounce back -- which all leads to long-term problems. (Reuters)
