My hypothesis, with no sauce,but 20 plus years of studying their methods.
Multiple vectors to weaken the immune system. From fluoride, lead paint, leaded gas and on and on to the present day.
Now we have vaccines, chemtails and the one this board does not want to talk about 5G. I have had 5G in my area for over a year, including multple apartment units in my building and a tall complex topped of with a dozen small transmitters.
I began to notice a burning sensation on any exposed skin, dry eyes, poor sleep and a general apathy and brain fog.
Then i remembered an artical i had read on the Active Denial System. This is a crowd control system used by the US military and its technical specs are practically identical to 5G.
Recently i checked my cloud account and found i had an old emf meter app for my phone and installed it. Norms are 50 to 60 micro tesla units and most rimes the meter read within that range.
I got in the habit of leaving the app on and checking it frequently. I found that at times the meter would read as high as 260+ tesla units and those were painful times.
Leaving it on and doing a smoke run 10 blocks away i found the whole area was bathed in 220 + tesla units of emf radiation. My only conclusion was this was 5G and it could be turned up and down at will.
