Oh, I'm not worried about it - it is what it is. Does make for some interesting encounters, though. Besides, as a relatively new EMT I'm hoping that more frequent exposure will help to eventually desensitize me. Sort of like the OP was referring to with blood.
Ever seen a medic get puked on, then puke right back on the patient because he coudnt move in time?
Anyone who remembers the 90's, Kodak moment.
