with due respect to the research work, i don't find anything particularly interesting about the finding. it's quite obvious that white collar jobs are more stressful. it's easier to work at the execution level because you are supposed to do what you are told to whereas white-collar people have to come up with thorough research and plans of actions which require creation and innovations. they are always at their toes with more responsibilties which become overwhelming at times hence more stress, which leads to depresstion. . it's not a rocket science! wow... only if money was everything......i wouldn't give it a damn! :P LooTe
