Fortunately, we are often able to make people feel more comfortable while their illnesses cure themselves. But sometimes, unwarranted medical intervention is fraught with enormous cost in money, pain and emotional upheaval. And the whole process may not be in the patient's best interests. I'm not exaggerating. Take a look at hospital patients.
Thousands die every year because of medical errors or fatal reactions to medications.
Doctors can certainly give therapy for such disorders, but not cures. Practitioners can postpone death and improve the quality of life, but medicine cannot ultimately master nature. This outbreak of optimism is irresistible for some doctors, who go to great lengths searching hopefully for a treatable disease. So they go overboard, ordering one test after another, to prove to themselves and to patients' families that an effort is being made, even if the physicians themselves don't really believe in a cure. Maybe we should run a few more tests, ha, ha, ha.
