If I were to go back in time with the knowledge that I have today about Electromagnetic Hypersensitivity (EHS), I would invest the money into changing the electrical characteristics of my body and exhaust that route first, particularly if no one else in the home is showing the condition. If everyone is sick in the home, it is probably an environmental issue that warrants expense on changing the environmental factors.
The USA utility power generation industry subcontracts out their dangerous jobs so that the bad statisitics will not be associated with them. Smart people avoid working for the subcontractors. I have worked directly for a number of subcontractors and overseen subcontractors and their staff were clearly sick, showing behavioral problems and overworked. In some cases they were blatantly breaking OSHA laws. OSHA covers it all up! Unfortunately, the problems can be traced back to OSHA and their wilful lack of enforcement of the law.
You are making few things on your new device or thing.... and you are just saying by your face "Look me, look what I can do..." - Oh, oh forgot sake just leave me alone. Because this is totally bullshit! (That's my opinon, you don't know as much as your face is showing... Your face is showing, oh look me I know everything, but unfortnately you just know little from everything)
