I used to be really deep into this rabbit hole. Theres a community of “biohackers” who do stuff like inserting rfid chips and magnets under the skin.

The magnet in the finger tip is what always interested me, but im too much of a chicken to seriously consider doing it because its not a medical procedure (you can’t just go to a doctor afaia and request to have it implanted - theyll just refuse to do it) so you need to do it with local anaesthetics that you can legally acquire, yourself or with a friend.

People who have done it have reported they became able to sense electromagnetic fields once they got used to its sensitivity, which is bizarre and awesome at the same time. They literally gave themselves a “sixth sense”
