Two totally different images here. One image is the mumbling guy in Office Space, the other was taken by Lewis Hines during the construction of the Empire State building. You might think the latter group had a higher risk occupation. Surprisingly, only five people died during the construction of the Empire State Building. Of course we're talking about 1930's statistics so there could have been more.
Anyhow, modern cubicle guy, if he doesn't exercise and eat right, is at a high risk for colon cancer, diabetes, heart failure, etc. The construction workers might have had an Italiam combo, but they burnt  calories and more by the end of the workday. Cubicle guy is burning 70 calories an hour tops sitting in his chair. It would take him two to three times as long to burn off those calories. Due to the lack of excitement, cubicle guy might seek out a couple donuts, or cookies that one of his coworkers left in the kitchen. The construction workers got enough excitement from their job to keep stimulated. So we wonder why so many modern workers suffer from obesity, depression, and in the case of males, dwindling testosterone.
The bottom line is that if you have a desk job, you better have a solid workout routined and nutrition plan before your desk job turns into a "high risk" job.
