Tattoos, Piercings, and now... Sensory Augmentation?

I am guessing that this topic does not pertain to many of you. But human beings do some interesting things to their skin and I wanted to share this with my readers.

Modifying the human body has become faddish the past several decades. I have seen innumerable piercings in every imaginable surface and orifice. Implants of rings, bars, pearls, and bones abound. And tattoos, well they are so pedestrian these days it is uncommon to see someone without ink.
