If I understand transmitters correctly, wouldn't ~directly under the antenna be a relatively low signal strength area?

Someone correct my if I'm wrong.

I see no reason to expect 20+ GHz to have similar effects to <2GHz radiation. At 20 GHz, almost all energy is deposited in the skin or eyes.

Disclaimer: Personally I don’t think LTE and co really pose significant health risks.

But, your claim that there were no changes to public health in the last two decades seems misinformed. Eg we have an Alzheimer‘s epidemic and an obesity epidemic, and rapidly dropping fertility rates. AFAIK some cancers are more prevalent. All these could be caused by other factors, but it definitely needs to be ruled out.

Not a scientist but did some undergraduate work in biochem. The answer might be in those two observations (Alzheimer's + obesity). As I understood it in most cases of Alzheimer's there is a deficiencies in the brain- glucose pathway/efficiency and as a result (some studies think) that the brain now have to work harder at extracting the energy from pathway and spend less time on maintenance+cleaning... (plague + metabolites). Thus switching the brain to ketones(or low enough carbs) will force brain to make use of this new fuel source.(better source ?). There is definitely a link to obesity and over eating on carbs/sugar/glucose

Just interesting that the two cases might be realted (Alzheimer's and obesity)

Ppl working in churches might also be more religious and follow a spiritual/different diet... depending on church... Could be a range of reasons why ppl in working in churches are more or less ill...
