All this tells us is that statistically no link with brain tumours can be found. There are many more illnesses caused by microwave communications. Insomnia, lack of concentration, feelings of pressure in the head, other sensory distubances, anxiety and depression. The effect of this over time on the individual and society should not be underestimated. Mobile companies and the government are making vast amounts of money from us and have never put anything into worthwhile research. Occasionally they chuck a bit of money at something like this to disprove something which was not provable in the first place just to keep us reassured while doctors dish out anti-depressants to stop us worrying about why our lives are so intollerable. I have not slept properly for 10 years now due a very low frequency noise. I have just discovered this noise is emmitted from the mobile mast antenna. 10 years without a decent nights sleep can really mess you up. MS, CFS, ADHD, EHS all caused by mobile comms.
