The average studies of cellphones and brain cancer have studied people who have used cellphones for five years or less. Sometimes eight years. Every study that has actually examined people who have used phones for 10 years or more, and is well designed, finds a 50 percent to an 800 percent increased risk. So that is why the Israelis, the Finnish, the French governments have all issued warnings.

Brain cancer has a latency in the population of 40 years.

The question is, do you want to play Russian roulette with your brain?

Get in the habit of never putting the phone next to your brain or body unless it's a true emergency.

The reality is, the way we've used phones and the amount that we've used phones has changed radically in the past five years. When phones were first marketed in the 1990s, it cost, for car phones, $3000 to buy a phone and the average person did not use it that much. They were very, very expensive.

A young child's brain has a thinner skull and the brain contains more fluid. The more fluid or fat in any material, the more it absorbs microwave radiation.

You can do something really radical, which is turn your phone off and reclaim your private life.
