I read that article (the one about angioplasty), and while I really do agree that for the majority of people with these symptoms, lifestyle changes would probably eliminate the need for angioplasty, it doesn't apply to everyone. My DH was dealt the card of horrible genetics and despite the fact he was a already a fit cyclist who ate well, he still had 2 80% blockages. It's true that if he had started cycling 10 years earlier and had started medication before he did (about a year before the surgery), maybe they would not have developed. But, he was not inactive, was not overweight, and ate better than most people.
I guess I just don't want people to think that lifestyle changes is the whole thing...
