There is a theory that one's cholesterol is high as a defense against some other disfunction in the body; that it actually fights for your health. Theoretically, if you lower it unnaturally, you may be taking away a vital weapon. I can't remember for sure, but it might be Westin A Price followers that has put this idea forth.
I agree, tho, Bee, if you start getting things checked when you are not sick, there's no telling what can of worms you will open. Obviously, with Bay's DH's family history, he needed to get checked.
