Howard will point and laugh, and not understand-- but he's lucky that he grew up rurally. If he lived in a clean environment, and didn't have prominent, significant pesticide exposure growing up Im willing to bet that he has no allergies or chronic health problems (different case if he did have that exposure).
The proof is already out there. People have been sequencing the microbiomes of Amish communities in comparison to those living in urban areas. Their kids, playing with dirt and being in the outdoors a ton has resulted in WAY lower susceptibilities in autoimmune conditions across the board.
I went to Kosovo in summer 2014, and asked around to see if anyone knew anybody with gluten sensitivities. Maybe like 80-100 people. Not a single person even knew what gluten was-- and quipped "Dalamon-- people would die here if they couldn't digest wheat". It can't be genetics-- my little brother is 100% Albanian and has gluten sensitivities. No parent on either side has relatives with it.
Another reason why this whole environment debate ****ing matters.
