The Quest to Beat Aging
Two humans that want to live a thousand years are the presidents of China and Russia. In September 2025, they were overheard talking about using organ transplants to extend their lives indefinitely. As a strategy, organ transplants have major shortcomings: it can be hard to find the organs, and just as hard to stop our immune systems from rejecting them. But people have invested billions of dollars in developing other approaches. Learn more about those listed below, then discuss with your team: if science does find ways for us to live much longer lives, would there be any reason to hesitate before using them?
- organoids | bioprinting | plasma transfusion | senotherapeutics
- cellular reprogramming | cellular rejuvenation | telomere extension
- caloric restriction | digital immortality | cryonics
Key concepts
- Repair vs. Rejuvenation
- Two different bets, and the whole shelf of methods sorts onto one side or the other. Repair replaces what has broken — a printed organ, a cleared-out population of dead-but-lingering cells. Rejuvenation tries to reset the cell itself to a younger state, which is a claim not that damage can be patched but that age can be run backwards.

Organ Transplants for Longevity (case)
The overheard 2025 idea: swap organs repeatedly and grow younger. Scarce donors and rejection make it the weakest route on the shelf.

What to know
-
01
Organ transplants are the weakest route on this shelf, which is exactly why the money went elsewhere. Donor organs are scarce and the immune system attacks foreign tissue, so a life of repeated transplants means a life of immune suppression. Bioprinting (your own cells, so no rejection), organoids and reprogramming are all attempts to get around those two walls rather than through them.
