It might help to remember that in many cases of need for kidney transplantation the term "save a life" may be exaggerated. Although the waiting lists for kidneys from deceased donors is long, it is shorter in other areas. Also, some persons with kidney failure do well on dialysis. Others are greatly hindered by the process of dialysis, but still survive for years until a deceased-donor kidney becomes available. Also remember that you are NOT the only possible living donor. His neighbors, co-workers, friends, alumni, club-members, etc. are all possible donors. Has he put out the word to search for possible living donors among all his acuaintances? Sometimes one potential donor mistakenly thinks that she/he is the ONLY option, when in reality there may be many others who are have not even been made aware of the need.
