we were told there was nothing to worry about

Back then we were told there was nothing to worry about; perfectly harmless, now we find out, well, actually they weren't. Stunningly, the most popular gadget of our age has now been shown to damage DNA, break down the brain's defenses, and reduce sperm count while increasing memory loss, the risk of Alzheimer's disease, and even cancer."
You see, here is a gentleman who wrote a whole book on the topic, not just a cutesy article for mainstream media. It's got all the studies, research, including these latest studies everyone is reading about showing how the cell phone radiation is causing DNA to breakdown, and that the cell phones are carcinogenic.
That's just scary stuff, and what about pregnant mothers with their cell phones strapped to their hips using the blue-tooth on their ear. Their brains are safe in that case, but how is their unborn baby doing there, I ask? Still more questions, but if you want some real answers, I guess I'd recommend this book to you too. Please consider all this. When is a phone not really a phone - when it is actually a cell phone. All those annoying little phones you hear buzzing where ever you go these days are radios. Just knowing this takes a little bit of the fun out of the devices. Never fear, there is more to these radios than just the transistors of old.
The original mobile communicators were called radio phones. Just like with any radio, there needed to be a transmitter. This meant that each car had to lug around a transmitter large enough to cover the 40 or 50 miles needed to reach a tower. Unlike today, each town or city only had one central antenna tower.
If the bulky equipment wasn't enough to deter consumers, the lack of channels available for calls would probably do the trick. Each antenna tower could only support around 25 channels. There just wasn't enough space to go around.
The birth of the cell phone changed everything and opened to world to mobile communications.
One of the first changes that came about was the addition of towers. Cities no longer sport a central tower, but are divided into smaller "cells" with a tower for each cell. This increases the range of the phones that are used. The cell towers eliminate the need for users to carry around large transmitters.
