Probably the most underrated quality of a good physician is their “poker face.” In the medical field, you see/hear/experience some messed up stuff and you have to suppress any reaction. It would seem that somebody like a trauma surgeon would have to deal with this the most, but it is rather equally pervasive throughout the specialties. Most of it isn’t graphic, like a compound fracture or facial injury, but more of what patients tell you or something you may discover during the physical exam. And it’s not good enough to mostly suppress your response; any reaction can be negatively interpreted by the patient.
I have recently discovered that I do not have the greatest poker face but I’m playing much more poker and watching graphic, violent movies to help.
