I have a lot of questions. Most of which center around controlling for other factors. 1. Is it income adjusted? 2. Is it diet adjusted? 4. Is it stress adjusted? 5. What kind of physical jobs? Or is it all jobs that aren't office oriented? 6. Is being a housewife considered a physical job? If so, have they looked at rates between housewives and women who work office jobs? 7. Is it hours worked adjusted? I have a lot more but I think people get the point.
