    The other theory I’ve heard that makes some sense is lead exposure. From 1925 to about 1976, lead was commonly added to gasoline. Lead is known to cause psychological problems including irritablity and general mood disorders.

    Pretty much everyone born during that period was exposed to aerosolized lead.

      I don’t believe that it’s lead; see my other comment on it. The lead reductions would have come much too late, and the falloff is too sharp.
