"So what's really going on here?

"We're getting zapped.

"If you pay close attention to your activities for just one typical day, you'll quickly realize that a new form of invisible pollution is all around you and, as you'll learn, within you, twenty-four hours a day, seven days a week. Granted, you probably don't have all those electronic gizmos in your house, and not all of these modern-day wonders are emitting dangerous radiation. Plus, let's face it, how much time do you spend sitting in front of your electric coffeemaker anyway? How long you're exposed often means more to your health than the actual strength of the electrical, magnetic, or RF field. . . .

"Think about what you did today:

"Perhaps you woke to the smell of coffee brewed exactly the way you like it by your electric coffeemaker, which you set on a timer the night before. Maybe you went downstairs, flicked on the fluorescent lights in the kitchen, pulled a frozen breakfast out of the refrigerator, popped it into the microwave, and sipped your first cup of coffee while you waited for it to heat. If you couldn't wait until you got to the office, you pulled your smartphone or cell phone out of its holster and checked your e-mail and then pulled up local traffic and weather reports. And after all of this, you took a hot shower and were thrilled that the new water heater let you take a long, luxurious one.

"You might have taken an electric train or subway to work. If you drove, you probably paid no attention to the power lines strung on the ubiquitous wooden poles that are as much a part of the landscape as trees, or the huge transmission poles lumbering across the countryside like sci-fi giants. If you happened to glance over at the car or passenger next to you, you likely saw someone else, like you, on a cell phone, starting the business day before it officially opens. At work, you might walk through an automatic door, take an elevator to your office, flick on the overhead lights, and boot up your computer.

"Then, at the end of the day, you reverse it all. Maybe you stop at the supermarket on your way home and buy a few things for dinner, which the checker whisks through a price scanner and tosses in a bag for you. If you're cooking from scratch, you preheat your electric oven, defrost the chicken in the microwave, and put it in to bake. You'll mash the potatoes you boiled on the range with your electric mixer and open the canned green beans with an electric can opener.

"Maybe you'll sit in a comfortable automated massage chair before you finish up a report on your laptop computer tonight, or huddle with your eight-year-old while he does his homework and then challenges you to an online game of Scrabble. You might watch a little satellite TV before climbing into bed, where you root around for the remote that controls the firmness or angle of your mattress.

"Everything you did, from making coffee to taking a shower to taking the train to buying groceries to going to bed, exposed you in some small or large way to electromagnetic fields, which are invisible force fields that surround all electrical devices. For many people, these invisible energy fields appear to be benign. They have no symptoms — at least, none that they recognize. But others seem acutely attuned to what others can't see, touch, or feel."
