Say no to being on-call 24/7 unless you are an emergency responder. Use a speakerphone, use a headset.

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.

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."

There is apparently an epidemic of tinnitus in younger people. Tinnitus is ringing in the ears and it can be disabling. Tinnitus is associated with cellphone use.

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.

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.

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.
