Once again, I feel the need to re-iterate this. When I was presented the scientific study paper by Joel, I asked immediately if it was invasive. It was talking about “mind control”. He assured me that it was not invasive, therefor I signed. It’s funny how I can feel things that were added to my body that are being stimulated externally by something that is invisible. It will need detected with a sensor and the source identified.
By definition anything inserted into the body is invasive. Even if it can be easily removed without surgery.
