What is the prime formula that doctors use day after day?
Answer:
Primum, non nocerum
(First, do no harm)
First do no harm.
You sit surrounded by the lobby waiting for the doctor who's 15 minutes late. A nurse call your name and escorts you into a small cubicle of an nouns room. You sit there for another 10 minutes. The doctor steps within, asks you what's the problem, he scribbles some transcription, pokes you and asks you to cough, writes you a prescription and 5 minutes later the doctor's gone. You earnings your co-pay and you're out the door.
That's about as formula as you can find.
