Ergonomists themselves concede fundamental flaws in their theories. They acknowledge that usculoskeletal pain has many causes other than work, and, while contending that physical exertion is hazardous, they also acknowledge that some degree of physical activity is healthful and that they cannot identify the point at which exertion ceases being good or benign and instead becomes a workplace hazard that must be regulated by the government. ..."
