How Yucky do you want it - our comes in different types and smells (Ha! thought I was going to say flavours didn't you! :chuckle
Basically you desensitize pretty rapidly until you reach the point where - well, and this is peculiar to ICU nurses and Physiotherapists, you actually get excited over sputum. "Oh! That's a good cough see if you can get more up!" End up having to restrain yourself from doing that when you are out somewhere.
There is a thread here about "You know you are a nurse if..."The one constant that everyone agrees on is that you know you are a nurse if you can continue eating lunch through a point by point description of an infected wound.
Often yo look back and think "Where did I lose my fastidiousness?" I can remember losing a lot of things innocence, childhood beliefs, car keys but when exactly did I lose the ability to believe that poo of any description was "Just too gross to be in the world"?
In other words you rapidly become less like "Clueless" and more like Sigourney weaver in "Aliens". Only if Sigourney had been a nurse she would have brushed that Aliens teeth first!!:chuckle:
