Dan Olmsted has been writing an interesting series of articles on Autism. On April 18 and 19, Mr. Olmsted published a 2-parter regarding Autism among the Amish. To cut to the chase, it doesn't exist! The only Autistic child he could find was an 8 year old named Julia who had been adopted from China. Mr. Olmsted (and Julia's adoptive parents) say that vaccines containing mercury have been the cause, and not some mysterious genetic defect that has rapidly crept into the gene pool of everyone else besides the Amish (which would be scientifically impossible anyways).
