The way I see it, the standards and recommendations of practice change from year to year, decade to decade. What does not change is the art of medicine, the ability to build a relationship with your patients.
If you can take away that from your training, you will do fine. The rest you can look up and read.
I remember one of the first students I was training here. He was a journalist. Was a journalist for nearly thirty years. He well could have been my father at his age!
But he was still learning.
This is a profession where even the old dogs learn new tricks, where the learning does not stop until the day you stop working.
