According to some recent information, the most unsanitary part of your doctor’s visit may be your doctor’s stethoscope. If there’s one symbol of the medical profession and its ability to help and heal, it’s the stethoscope. Either that or that snake thing. You know what I mean. But who thinks snakes are sanitary? Nobody. Who thinks stethoscopes are sanitary? Probably quite a few people. But apparently, that’s not the case.
