Röbi will die soon. His life expectancy is between one month and one year. An insidious cancer has attacked his lungs. He has known this for two months when he went to the doctor because of back pain. He does not want chemotherapy or radiation, they would only postpone death for a short time. In addition to this serenity, he knows very well that in the coming months he will also have moments of despair, days of sadness and nights full of pain.
