Not only can interference effect your physical health but, more importantly, it distorts your perception of what is going on in the world and compromises your ability to respond appropriately. Your brain is primarily a responsive organ, it does not generate all the information the body needs and tells it what to do. The brain only responds to the information that it is given by the nervous system. If you are sub luxated and have garbage going into the brain, you can only get garbage coming out. Posture, for example, is a brain dysfunction because of the bad information the brain is being given.
