Until "recently" we didn't have mass vaccination programs. Until "recently" we didn't have autism and all these other crazy immunological and neurological problems. And just "recently" the majority of mother's stopped breastfeeding. So even you can do 1+1= 2 right?

Mothers start to bottle feed more, the govt and medical start producing and vaccinating the pop in droves and now 40-50 years later we've got problems that nobody knows how or why.
