Don't laugh. Some people think that they are animals. Why then do surgeons not surgically attach a tail?
That is a good question.
They do, sometimes...…...I saw a bunch of clickbait photos of surgical alterations of (well-tattooed) individuals who had tail, horns, and large canines implanted medically.
Sexy now, but what about when they're 74?
It does seem to me there are some real ethical issues about cutting breasts or penises off children of 18. Or implanting people with horns or vampire teeth. Oh, Freedom!
