You go and get your yearly physical.
After reviewing your blood report, the well-meaning, Harvard graduate doctor tells you that your cholesterol level is too high. She tells you you need to be on statin medications to lower your cholesterol level and to eat less eggs and cheese. This bothers you.
You really don't want to takes any medications nor do you want to give up your soft boiled eggs and brie. You've read and heard about the controversy surrounding cholesterol lowering medications so you go to another doctor to get a second opinion.
The second doctor, a well-meaning, Yale graduate says your cholesterol levels are high by current guidelines, but that research reveals that it doesn't really matter that much if at all what your cholesterol levels are. That statin drugs damage your liver and nervous system and that eating eggs and cheese do not raise blood cholesterol levels.
One of them is wrong.
