Tapio Videman says back disorders in the working population are among
    the most costly illnesses in developed countries around the world. Disc
    degeneration is the main suspected origin of severe back symptoms and
    the main target in spine surgery. But Videman, a researcher in the
    University of Alberta's Faculty of Rehabilitation Medicine, wants to
    dispute the common perception that disc degeneration is caused by
    physical loading, the pressure put on the spine that comes with, for
    example, frequent lifting. Videman's research team found that more
    physical loading may in fact slightly delay disc degeneration as it's
    known to be good for the bones, muscles and tendons.
