We get dopamine in the brain when we like something a lot. Well, cellphones stimulate dopamine, too. So it really is the case that there are some people who are pretty addicted to these devices.

The whole idea of what is evidence for causation in epidemiology cannot be separated from tTindustry understood that if they could raise doubt about how you could conclude something caused cancer, that they put so much effort into getting so many receptive public health authorities to say, "Well, causation requires that these five things be met." So that is, in fact, nonsense.

It's true that non-ionizing radiation lacks the power to have damage. But its damage seems to come from its modulated signal. So every 900 milliseconds, if you have a cellphone in your pocket, it's getting half of that radiation which is getting into you as it seeks the signal from the tower.

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.

Where people are using phones in rural areas their risk of brain cancer is higher than in urban areas.

If you are a physician and someone comes to see you with an absolutely incapacitating headache or a swollen arm, you don't tell them, "Come back in 10 years when I've completed my study and I'll see what I can do for you."

When the signal is weak, the phone is working more, you drain the battery faster, so only use a phone when the signal is weak in a true emergency.
