I have to admit that before getting into the "natural mission", I virtually ignored most of the message my body was telling me. Yelling at me actually. Looking back now, it seems the dialogue (one way), was always there and often quite specific.
It would say things like "are you completely crazy! Don't take this birth control pill it's REALLY not good for us" and "If we stopped eating now we would feel satisfied and energized but if we keep going, we're going to feel like sh__.
As you may know from personal experience, cumulative ignor-ance usually leads to pressure build-up and inevitable explotion that demands attention. For me that was "quit smoking or you will die cause you can't breath anymore".
I find that the more I do listen, the more I hear. Before working on a new formula, I take the raw ingredients and apply them directly to my skin to see how each one feels. I also do this with competitor products. It's really nifty 'cause you get quite a bit of info that way.
I still play deaf of course, but hopefully not quite as often :)
