Several of the jws I know have recently graduated/incorporated wifi sensitivity into their (self) diagnosis of chemical sensitivity. They seem to be particularly terrified of the new 5g, with some even believing that it's the new 5g that's causing coronavirus in China.
The fact that even though they maybe able to turn off their own wifi but will still have all the other wifi signals around them doesn't seem to occur to these Jws. Many have outlandish gadgets and therapies to combat the wifi signals.
Most seem to think that 5g will bring about armageddon by killing everyone in its reach.
