Wonkblog: Researchers have determined how many years of life you lose to a stressful job

People often like to groan about how their job is "killing" them. Tragically, for some groups of people in the U.S., that statement appears to be true.A new study by researchers at Harvard and Stanford has quantified just how much a stressful workplace may be shaving off of Americans' life spans. It suggests that the amount of life lost to stress varies significantly for people of different races, educational levels and genders, and ranges up to nearly three years of life lost for some groups.
