Look at alcoholism...keep drinking and it will continue to deteriorate your body. Keep smoking and eventually you will not be able to breathe. If you have any disorder in your body you ultimately know that a change needs to take place. I am hypoglycemic, allergic to dairy and gluten so I know that I should avoid sugar, dairy, wheat, pasta, and many other products processed with gluten. If continue adding these items to my food then my body pays a price, and ultimately I am causing my own deterioration.
Living in moderation and balance can be a challenge especially when we are all faced with external stress, challenge and life in general. We all have choices, and we all can learn how to better take care of ourselves if we really want to.
There are never any guarantees, I might walk outside later and get hit by a bus. This is a simple suggestion that if we could remove all thoughts of what we've been taught and learn a new set of disciplines to live by what do we have to lose? A better life, without pain? Either way we will have a better experience here or after, why not try it's better than the alternative, not trying.
