Beating the Odds

What are your odds of having high blood pressure? It is a simple question and all you have to do is ask your physician, correct? As famed college football announcer Lee Corso likes to say, “Not so fast, my friend.”

Your internist may take your blood pressure, tell you it is 131/81mmHg, and say you are fine. What is going on?
