Practically it's impossible to lose a Dermal Anchor! As its name implies it's anchored under your skin. Solid and tight. Only piercers are able to remove it. Well for me it was even possible to lose one today, for some reason it already stuck out half-way and I had to give him relucting the killing stroke which did suqeeze my heart a little bit much. It's the third piercing in row I lost to afteraffects of getting stuck. I called him Dermy. Sigh.
BUT watching this makes me happy again.
