For years, I was a walking cerebrum.  Most doctors are. It’s what we’re trained to do. As a physician, you can’t sleep when you’re tired, eat when you’re hungry, pee when your bladder is full, rest when you’re sick, get it on when you’re horny, or stop operating when your arms are killing you from manipulating heavy instruments in a small dark hole. So you learn to dissociate from your body. It’s a healthy adaptation that gets you through medical school and residency and helps you keep on keepin’ on when you feel like quitting.
