I've been vegan for over 30 years. When my health allows, I exercise. I have never smoked. My BMI is 20.5. I do "all the right things." Yet I've almost died several times and have multiple ongoing chronic diseases. After heart surgery, it took more and more drugs to get my cholesterol down to where Anne's is naturally, even though we eat the same thing.
So please stop saying that health is a choice.
