I know plenty of EM docs who work all the way through retirement. Before med school, I worked in an ED as an orderly. I asked all the physicians there (they were all EM trained, mostly from Wake Forest)... if they planned on working in the ER or they would switch to a clinic or FP setting... uniformly they all said "No way... this is what I was trained in, this is what I love... I'm doing this until the end..."
There you go.
