Damned lies and statistics...
What happened to men between 30 and 40, probably the age range of increasingly more and more "normal" (married) fathers?
I would give this report more credence if the stats were tabulated continuously by age, including the youngest, as well as the oldest...
There is more evidence that mercury in vaccines is the culprit. In fact you can google a large study in England and many in the U.S. that are extremely compelling.
I personally have a friend who has 3 autistic children. (Can you imagine?) Their doctor, who happens to be one of the better specialist's in this field, said that the vaccine plus an IV given to the oldest contributed excessive mercury at a young age. The other two have been found to have an unusual sensitivity to metals.
One study in the U.S., examined Amish children who, as a rule, are not vaccinated. Not one case of autism in this population.
