Implants and body modifications have become popular DIY procedures known as "grinding" or being a "grinder." Some modify themselves at home by inserting magnets or chips under their skin for novelty or purported health benefits, despite medical risks. The underground community shares techniques online but doctors warn against non-medical body alterations that could lead to infection or rejection by the immune system.
