We are told that we have free will in the United States. Of course, if your free will imposes on my free will, then we have a problem. However, for the most part, we do have choices that we are free to make. Your health choices are no different.
You can choose to be healthy. Today, at this very moment, right now, you can choose to be healthy. When you make this choice however, there is a consequence. You must then actively choose healthier choices.
You see, its your choices that tell me, and you, whether you are actually choosing to be healthy.
If I gave you the choice of a nerve system that is free of interference, or one that is interfered with, I think it pretty obvious which one you would choose. This should be your first choice when choosing to be healthy.
