"There are probably hundreds of thousands of ways to develop environmental illnesses, 2-butoxyethanol being only one."

Well, I can see where people would think that ... because it is not realized how widespread the exposures are ... how prevalent it is & has been for decades.  It doesn't get blamed for the diabetes, the chronic fatigue, the autoimmune issues nor the cancers & birth defects that it causes.

It should be suspect for Pres FDR's death; Eisenhowers Chron's & explosive diarrhea ... (But did their doctors recognize it?) http://www.valdezlink.com/pages/fdrikevets.htm

It should be suspect for the cause of CFIDS & 'gulf war syndrome'

I think exposure to 2-butoxyethanol should be another reason to approve disability claims for military & insurance claims for civilians
