A study published in the British Journal of Sports Medicine found that strenuous physical activity isn't good for you.
In fact, men with physically demanding jobs may be at an increased risk of death.
Compared to men who worked jobs requiring little to no physical activity, men who worked physically-demanding jobs have an 18% increased risk of early death.
So what gives? Why is some physical activity good for us, while some aren't?
There seems to be a difference between physical activity performed at work, and physical activity done in leisure time.
These differences are what increases the risk of early death.
Are other factors contributing or is it all physical?
