With all the EMFs ( Cell phones, computers, WiFis and routers, and now some people having the 5GHz routers in their apartments) my whole apartment building isn't a very healthy place to be (this is a typical situation, now, alas, all over, not just in NYC, where I live ). My thymus gland tested weak, using Applied Kinesiological testing. My my lovely Energetic Bracelet EMF Protection 7.83 Hz Resonance Bracelet ( I bought the rose gold plated tennis bracelet) came in the mail yesterday. I put it on my left wrist and tested myself, again. STRONG! What a relief to know I'm protected!
