Baz remembers first seeing an amputee when he was a 4-year old boy in Liverpool. By the time he was 7 he had begun to think, "This is the way I should be." It was not until Baz was in his 50s, however, that he actually had his leg amputated. Baz froze his leg in dry ice until it was irreversibly damaged, then persuaded a surgeon to complete the job. When he awoke from the anesthetic and his left leg was gone, he says, "All my torment had disappeared."

In the meantime, psychiatrists are no closer to understanding the condition, and they are proposing no therapy other than amputation.
