i'm 36 years old..just realizing that that the asthma and head shaking are from mercury poisoning. First started getting ear pains and asthma, head convulsions (electric shocks) around 12 years old. that's around when i got braces and had 11 fillings put in. I'm going to shoot the ADA president. ok..not really but i can dream can't i? Maybe i'll just tie the whole association down and pour mercury down all their throats and stick some up there A-holes too.
