Aaron, you taking the lowest possible interpretation of the word "maintain" simply shows that you have no actual relevant response to this matter. So as a result, you turn to stupid comments that you hope will distract others from the fact that you don't know what you are talking about. If it makes you feel better......
As for the chin thing, I don't know what made it work in your circumstances because I'm not there to see it and analyze it. However I can assure you that without a doubt, it is not your body amplifying the signal or acting like an antenna and fillings in your teeth have play no part in it.
