 increase in household mold is from making houses too tight, trying to insulate too much.

I wonder how much of our current IQ loss is due to these environmental factors

 @Sick Burn, Bro this would be fixed with the ray peat diet. 
 Most of our degradation is environmental, however one must not forget the epigenetic factor and the fact that epigenetic expressions are inheritable. So you can fuck up your kid with toxins, and in the same process fuck up your bloodline because he'll pass this shit along. It's odd because it's super easy to fuck it up, but is a generational endeavour to unfuck it 
 I wonder if radon is increasing for the same reason? 
 I work in building conservation and there's a consensus that making pre-1900 buildings air tight is a great way to fuck them up. However I've increasingly realised that that applies just as much to modern buildings.
