I'm not sure. When my Doctor was reviewing my Heart Sono, Carotid Artery (whatever the Hell it was called) Sono, and Cat Scan, he said, "Oh you have, blah, blah, medical term, blah". I said, "what the hell does that mean?" He said, "you have floppy and leaky heart valves, but don't worry about it because they aren't bad." Then he said, "If it was the bad kind you would have to have (some more medical crap) a camera put into your heart and we would check it out. If your symptoms aren't any better by September we will consider having (whatever the hell the medical term for the camera in the heart is) and have you studied at Johns Hopkins."
I thought I was being the good patient by asking him what the hell he was talking about, but his floppy, leaky heart valve that isn't bad response didn't help.
The CT results were good, the Carotid whatever the hell it is results were good, but the Heart Sono thingy was when he said the floppy leaky valve thing.
Or do you envision Charlie Brown's teacher as her physician? And she the student leaving the classroom no more enlightened than Sally after being given a big assignment?
