In this picture taken on December 9, 2022, thoracic surgeon Francesco Cassiano (R) holds a lung as he performs a transplantation operation in an operating room at the Foch hospital in Suresnes outside Paris, following the lungs's removal operation earlier in the day in an undisclosed hospital in eastern France. - During an organ transplant, from the moment the organ is removed from a donor, a "race against time" is undertaken until the transplantation. A feat made possible thanks to the human chain that will be deployed for several hours. (Photo by Christophe ARCHAMBAULT / AFP)
