Great points as vibration just does not come from industrial exposures; in fact the more we mechanize jobs which we used to and probably still should perform; such as snow blowers (use your shovel as this is great exercise); motor boats (how about a paddle or kayak paddle?); electric tooth brushes (well these do seem to do a better job for our teeth than manual toothbrushes). The more you and I used mechanization versus manual tasks the more our hands, forearms, eyeballs even are exposed to vibration. The Ergonomic Team at OPC Inc
