Roland Diewald has suffered from diabetes and circulatory disturbances for 40 years. As a result, his toes, forefoot and lower legs have had to be amputated, bit by bit.
Romy Ziltener, from the Swiss town of Weesen, has a long history of suffering. Since childhood, one of the pensioner's legs has been 2.5 centimetres longer than the other, and she is afflicted with back problems.
