When the spine is flexed, twisted, or otherwise bent out of its natural or neutral position, the discs are compressed and lose the blood supply that is their lifeline. By periodically moving and stretching the spine, he adds, needed fluids move in and out of the discs. Simply placing the work at a convenient and comfortable distance from the worker can make a world of difference.

More than ever before, he says, our 24-hour society is contributing to a highly stressed population. As a result, Bunch says, adrenaline, which depletes the body of vitamins and minerals, remains in the body. Since we cant get rid of stress, we must get rid of its effects. One antidote to stress is a naturally occurring substance known as endorphins, which are released, as many people know, by exercise which can lead to a greater sense of well-being. Unfortunately, another means of releasing endorphins is the consumption of fats and sugars.
