as a former radio and television technician, I know that our old 2 and 3 Giga hertz television frequencies are now used for telephony and data and have always warned against being in front of the antennas .....
Looking at the increase of brain cancer while other cancers stayed the same was the proof for me. Not only has it "more than tripled", analysis of the data that includes estimation for the fact that these increaes are delayed as it takes exposure time for the cancer to develop. They estimate it is actually going to lead to a 20x increase or more. How cancer causing EMF are is by rule of thumb frequency * power. 5G has much higher frequency than 4G, and its power is directional, so it aims and concentrates all the power at your head when talking on the phone. 5G is powerful enough at affecting brain waves that it was the frequency band governments experimented with for behavior control.
