Most of us realize the impact of our friends’ behaviors: smokers tend to hang out with other smokers, exercisers with other exercisers, Yankee fans with other Yankee fans. Like begets like.When we surround ourselves with people who have similar habits, they validate our choices and we feel supported.  If everyone around you is eating junk food, then it’s easy for that to become the acceptable norm for you.But what happens when the people we trust to keep us healthy—our doctors—are themselves unhealthy?
