content: Simple experiment that shows the viscosity of water is changed by microwave radiation:  https://pubmed.ncbi.nlm.nih.gov/24856870/ So now the viscosity of water has been altered everywhere on the planet, and you think this has no impact on any biology, and I have a bridge to sell you. And this is just one single effect. There are many other effects, equally soundly based on physics, that in fact it would be surprising if microwaves would NOT affect biology. Physics says it must. Maxwell's equations says it must. Only people sticking their head in the sand think it won't.
