There are two reasons we can say with certainty that this technique works, including a scientific basis. First, we have 60 years of empirical data: the founder of this technique and Bill Cordingley have used this method for 6 decades, on thousands upon thousands of people, with consistent accuracy. Second, there is a scientific basis for the method, put forth by a physician. That is, our faces are actually quite changeable, and alter their appearance according to the facial muscles we use and the hormones our bodies create in response to our life experiences. So, over time, our faces reflect who we are. But nothing “proves” this technique more than using it. So, Bill Cordingley always invites people to try it themselves. Experience has consistently shown that once they learn what particular facial features mean, there is little room for doubt that it works.
