Later the density of 3G, 4G, 5G WiFi and mobile phone increased enormous. I had to shield my house against the wireless communication signals from outside and of course there is no WiFi in my house. And I also can not use a mobile phone, because I feel sick during and after using it. Also after visiting a clinic or hospital for more than 1 hour I am exausted for 2 days or more. I had to quit my job because the wireless frequencies of WiFi and the use of smart-phones by my colleagues made me sick. I also cannot go to a cinema, theater, concert, restaurant or travel by air, because Wifi and phones So my social life is almost on hold.
