Just read "Pervasive Doctor Burnout" Great to know as I start this wonderful field.

I don't know about the research. It's a little suspect.
I just left a drinking party with a whole room
full of interns and residents in medicine and surgery.
They all were handing their liquor in excess just fine. Happy about nothing mostly.
