Weightlifting

[Carrol Cox]

I read years ago that the most common disability among hospital employees
was back trouble, and that most of those disabilities could be reduced to
one label: understaffing. (That is, one lifting when the task calls for
two; two lifting when the tasks calls for three; etc.)

Does anyone know of recent studies that would bear on this? Is it true? Is
it worse now than  it was 10 or 20 or 30 years ago?
