1. Exceptional longevity of transplanted organs
Users were struck by how a kidney can remain functional for far longer than usual—effectively “100 years old” after being donated from a mother to her son.
- “Mom donated a kidney to her son and she would have been 100, making the kidney effectively 100.” — latchkey
- “still fascinating that the organ could live that long” — agumonkey
2. Organs syncing to the recipient’s biological age
Several commenters noted research suggesting transplanted organs take on the age (or biological state) of their new host, which influences long‑term function.
- “There is an observation that donated organs sync to a biological age of the recipient.” — d_silin
- “transplanted organs adopt the age of the recipient, contradicting the hopes of people who want to live forever by replacing their organs regularly.” — zorobo
3. Personal donation stories and typical graft survival
Many shared their own experiences, highlighting that a living‑donor kidney usually lasts 15–20 years, with rare cases of re‑transplantation or extraordinary longevity.
- “I received a kidney transplant from my mother at 16. It lasted 19 years after being transplanted.” — phibz
- “a living kidney donation typically lasts 15 to 20 years… this is the longest lasting transplant this hospital has ever done.” — astura
- “I donated a kidney to my Dad in 2000. It gave him an extra 23 years with us.” — JohnTHaller
- “Organs can be transplanted twice but it's very rare… it's called retransplantation.” — gertop
