IQ destroying chemicals, and their abundance.
Brief video with citations, explaining the chemical assault that is overtaking our young and our future.
IQ erosion is probably not directly cumulative ( i.e. my arrival on the number 57, a drop in the 20 range is probably more realistic ), or it can even be worse (synergistic). No one really knows, as studies are primarily done on individual chemicals and not multiple different exposures.
If you have any further questions or clarification on any study mentioned, please feel free to inquire with me. – Ralph Turchiano
