Do you have a ringing in your ear? You are probably being tracked by the NSA!

Howdy GS,

There's a practical step that you could take,to isolate the source of the ringing in yer ear,you could construct a tin-foil hat and see if it interrupts the signal,but yer best bet would be to construct a faraday cage and git inside it and git a frequency sniffer,that can tell if ya have any unsual frequencies of electromagnetic radiation present.

Have a good one !
