just as one cannot prove a negative, the absence of something is proof of nothing.
i havent been this healthy since i was ten. that was 39 years ago and 3 years before i started smoking. it was also before i got any dental work done.
i feel great and have no impairments except for a little fuzzy reading vision and a supposed genetic hearing problem. i also dont get sick. everybody else can do what they want. i am mercury and fluoride free!!!!!!
