Interesting thoughts, Richard.

As for autism, last I read the genome project suggested (not yet clear) that is is a genetic mutation from the father's side.

Friends of mine have 2 autistic children (or 4 kids) and neither parent uses drugs. Mom stayed away form alcohol the entire pregnancy all 4 times. And when she and dad due drink, it is a glass of wine with dinner. (Hey, live out that in California, in wine country!)
