I appreciate the feedback. You could be right. My father worked in aviation fuel research in the 1930’s thru 1950s and died at the age of 89. To support your case, could I have the reference to 'The guy who invented it even suffered lead poisoning." And where I can find the reference material for “lead-induced behavioral issues by kids who grew up in the heyday of leaded gasoline 20 years before.” Thanks.
