There is a time and place for electromagnetic shielding and I regard it as a last resort due to the long term biological problems that I have observed with it over the years in plant growth experiments.
There were three people in my home and I was the only one showing Electromagnetic Hypersensitivity and reactivity to the radio frequency transmitting utility meters. For these reasons I did not shield my home and took the route of adapting my body to the toxic electromagnetic environment.
I have never heard of an electromagnetically hypersensitive person recovering from the condition using shielding and Faraday cages, they just seem to become social lepers due to their increasing reactivity to the city environment and addicts to their shielded environment.
