Greenbelt residents may love their cars and when it causes problems for them, they take their car to a mechanic and trust their professional experience and training in diagnosing a problem and properly repairing it. The same holds true, of course for doctors. But the human body is far more complex than a car. And unlike cars, which have a finite number of makes, models, and identical parts that could fail, every human is different. What causes an illness in one person may not be the same for another person. And even when an illness is properly diagnosed, the treatment and prognoses often varies from person to person.
Similarly, if a car mechanic fails to properly "treat" a car, and the car owner drives away only to find the same clink or clunk while driving, the driver simply brings it back for further diagnosis and a new "treatment." But for patients who experience a doctor who fails to properly diagnose or treat an illness or injury, the repercussions could be far more severe, and possibly deadly.
