Cardiac Petrification Disease

There was recently a report that medical students have a hardening of the heart during medical school, particularly after the first/second years. It seems medical school sucks away their human spirit, rendering them less empathetic and more cynical. I just finished taking my umpteenth set of exams today, and I certainly feel like an empty shell of a person. Or maybe that's just because allergy season is now fully upon us, and I'm just feeling empty because I've blown all my contents into tissues. Still, I wonder what happens if one is already jaded before even hopping onto the bottom rung for the long climb up the prestigious medical ladder? Does it get worse?
