my autism theory-
All the Woodstock hippies who took chemical drugs scrambled their systems and it skipped a generation.
Their grandbabies are paying the price.
Just an opinion.
The harsh, politically incorrect truth is that many women party heartily with drugs and alcohol not knowing or not caring they are pregnant. You don’t have to be an embryologist or neuroscientist to speculate what these foreign substances are doing to developing brains. Widespread illegal drug use among women was relatively rare in the United States prior to 1965. Since then it has become very common.
Woodstock was not a generation. It was a bunch of lefties/hippies. Most of the boomer generation was not involved in that insanity. Many were in Viet Nam.
