I consider everyone is electromagnetic sensitive -stick your tongue in a light socket and see what happens. Some of us are particularly sensitive such as my self, I generally find a sustained environment of 500 microwatts/sqm as my trigger level. Personally I feel many are very sensitive, they just have not recognised the levels of radiation are what is causing the illness

In regard to putting your feet on the bottom of the poll doubt it will help. put them on dirt or better grass and even go one step further knell, touch your forehead to the ground.
