I have kidney disease - due to the invention of a blood pressure tablet I am sitting in remission for now - though the dreaded day may come yet when it marches on again. I have a friend who donated her husband's organs and one of the receipients wrote to her, she had got a kidney. Not only did it now free up her life because she was now well, but her mother who had been her carer and getting old, was now free in her life too. So a donation of an organ has multiple effects on receipients and on their carers too.
