None of them feel pain. It's like the pain nerves don't extend from outside their body and into doctor's body and manifest as pain in the doctor's nervous system, because when a doctor decides to fuck with eg a senator or CEO, that's different, I've seen that, the doctor recognizes that pain.
Particularly a Silicon Valley moghul who asked for a colon exam and the doctor denied it, meaning he couldn't get it since he didn't have a doctor's permission, meaning he died of colon cancer which went undetected too long, and wrote a book as he was suffering about how much he hated that doctor. That doctor apologized, though really he should have gotten cancer up his own tract as a consequence, let's be honest, that would be justice if GOD carried it out. That moghul should have sued for malpractice, gotten the guy denied from even teaching medical school, end up mopping up at the IHOP that's the afterlife of a callous doctor. Drive a taxi after fucking up, just like everybody else. If that. Beg.
A doctor recognizes pain when it is his own. Empathy or consequences, one of the two.
