Stock Photo - 40-year-old Concetta Tatti, suffering from the rare illness 'juvenile dermatomyositis', driving in her wheelchair on a street in Groebenzell, Germany, 17 February 2016. Tatti, measuring 1.46 meters and weighing 28 kilos, got infected with the phlogistic skin and muscle disease, which makes the immune system fight the body, when she was three years old. As most patients do not reach Tatti's age, medical science has almost no experience with cases like hers. 15 assistants care for the generally happy Italian woman in shifts.
