The article I read said that they found at least one surgeon (in Britain) who was willing to amputate a healthy limb from such a person.
The human mind is prone to all sorts of delusions.And there are some physicians who are willing to placate such people.
I'm guessing that this is the origin of the tale of the King with No Clothes.
He was not the only one that had this delusion - it was “a thing” at the time, with numerous people afflicted with it. It lasted for 150 years.
Not unlike the mass hysteria of mostly girls all through out history (crying girls in Malaysia, screaming girls in Massachusetts, etc.)
Since 2010 the number of boys identifying as girls is up something like 100% (double). The number of girls identifying as boys is up something like 2,400%!
From Wiki: “Concentration of the glass delusion among the wealthy and educated classes allowed modern scholars to associate it with a wider and better described disorder of melancholy.”
Interesting. The majority of girls thinking they are boys are white girls from upper middle class families and above.
