A young doctor had been treating his patient for diabetes for quite some time, using alternative methods, with excellent results.
His nurse, however, believed that the patient should be on insulin.
As a result, the patient had a few doubts and decided to ask him about it. She did so in the following manner: "Doctor, If I were your mother, would I be on insulin now?"
To which he replied, "Absolutely not!" Then, after a short pause, he added, "She doesn't believe in doctors!"
