Some act out their desires, pretending they are amputees using prostheses and other tools to ease their desire to be one. Some people with BID have reported to the media or by interview over the telephone with researchers that they have resorted to self-amputation of a "superfluous" limb by, for example, allowing a train to run over it or otherwise damaging it so severely that surgeons will have to amputate it. However, the medical literature records few, if any, cases of actual self-amputation.
