Please note: This is a companion version & not the original book. Sample Book Insights: #1 Neurosurgery residency. Rule number one: You aren’t the same when the air hits your brain. The brain is like a 1966 Cadillac, with bricked-in personality. You can’t play with it. #2 The rules of a surgical residency are: never stand when you can be sitting, never sit when you can be lying down, never use the stairs when there are elevators, and always eat and shit at the first available opportunity.
