Because its INJECTED instead of going thru natural defenses!

THATS why you didnt see flappers then...altho i would say there would a been some. And as you say, they were eating the fish!

AND if you look at communities that eat tons of mercury laden fish (I believe there was one city in Japan a study was done) you find little to no autism...And when you think about the Omega 3 and 6 fish oils that counteract the effects of mercury poisoning being heavily injested along with the mercury you find your solution.

Also, i dont think its JUST the mercury...I think its a combination of the mercury and the viruses...both injected into the bloodstream...the mercury sets up the situation so that the viruses can do damage.
