Research reveals that 50% of Americans may have lost 5-7 IQ points if born between 1955-1966. Seems the addition of lead to gasoline created atmospheric neurotoxins.
I believe the additive was withdrawn in 1966. And I just thought the math was getting more difficult as I progressed through high school.
