I always get it. I turn off everything in my room at night, the wifi, which isn't in use by any device, is 15m away on the opposite side of the apartment.
It disrupts sleep and our brain function. It interferes with us receiving the cyclic radio signal created by the sun and the rotation of the earth.
And yeah, I think that it makes people weaker and more susceptible to manipulation, and stupider, and they even defend it by saying you are crazy for believing that.
They are in a dream, anaesthetised, running programs they don't realise are against their own interests.
