As a patient, I have zero patience (pun intended) for the arrogance attitude from anyone in the medical profession. Only one GP has had the temerity to pull the "X years of medical school" card on me - which I promptly trumped with "50 years inside this body - which gives me MUCH more insight into what is "normal" for me than your pathetic 7 years drinking and carousing with your school mates." Needless to say, I no longer patronise that medical office. (Am in the States, no NHS here)
