"Fibrodysplasia Ossificans Progressiva is a disease where the body’s repair mechanism is completely broken, and starts “healing” the fibrous tissue (muscles, tendons and ligaments) by turning them into bone. Your whole body is slowly being petrified. There’s no known treatment for the 450 sufferers worldwide, and in one famous case a sufferer survived up to the age 40, at which point his entire body, except his lips and transformed into bone, leaving him completely immobile."
