There is a chemical exposure that is very common from WWII days to the present ... for both the military and the public: ethylene glycol monobutyl ether or 2-butoxyethanol. I suspect it is the root cause of President FDR's death and the cause of Hitler's and the Pope's Parkinson's. It should be suspect for the cause of CFS or CFIDS.

Bomb fumes in the eyes of WWII soldiers could cause this, and subsequent birth defects of brain tumors, leukemia, Type 2 diabetes, autoimmune metabolic problems, NHL which are dramatically increasing these past decades ... including infertility; sperm counts are on the decline during that same time period.

For those with DIRECT exposure (not birth defect effects) ... To find the harm of 2-butoxyethanol - you have to prove the fatigue of CFS, CFIDS (Doctors say they don't know what the fatigue is):

- Autoimmune hemolytic anemia

Thankfully, everyone doesn't come down with everything this chemical can do. The biggest clue to its harm is blood in urine. Next clue is red blood cells that are small-sized (immature?) You need to know that, because liver and white blood cell tests don't read right if red blood cells are predominately immature.

I learned about this chemical as it was stated as the chemical of harm for the Exxon Valdez oil spill cleanup workers ... however, these workers' health look 'just like' that of the soldiers with gulf war syndrome ... and more like what happened to the Vietnam vet (than dioxin would). We would do well to notice the similarities in how they became ill - not the differences.

Everyone is at risk regardless of their age: especially housewives who clean & painters.

Tried?  Grouchy, etc?   Pets can be harmed, too
