My work in a professional video production involves me spending long periods surrounded by electrical appliances, computers and industrial VCR’s etc. In addition, my office is right next door to a cell phone transmitter tower. Last year I was becoming increasingly fatigued and was suffering from a loss of concentration while working. A business associate and friend suggested that electrical fields could be a factor and that a device called a “Blushield” may be worth trying. A Blushield was duly installed in my office. Ten minutes later I suddenly realized there had been a profound change in the atmosphere of the room. From a vaguely ‘prickly’ feeling the air conditioned room had somehow become fresher feeling.
