anybody who works in the emergency services (or, at least for the police which is my experience) is working in a toxic environment. They are all friends with the police, firefighters and doctors who often see horrific things on a regular basis
In the emergency room, having examined the medical imaging results, the doctor explained to me that, yes, in fact I was having a heart attack, and based on the scar tissue on my heart, I seem to have had one six months earlier. And where was my ex wife so I could throw THAT in her face?!?
