Stethoscope

Everybody wants to hang a stethoscope around their neck and pretend to be a doctor.  When I see a stethoscope around the neck, I think he or she pretends. My Dad use to say, "That man knows that he knows, and he knows  not, and he knows not that he knows not." A physician in those times would not be caught dead with a stethoscope around his neck. --- Ostentatious in the extreme and it remains so today. Two thousand four hundred and fifty years ago Hippocrates wrote that the science be limited to those worthy of of the privilege -- no small matter.
