No, repeated organ transplants won't make you live forever

Russia Prez Putin had hinted at the idea which is almost certainly false

What do world leaders talk about when they think we're not listening? This week it was the idea of living forever.

Russian president Vladimir Putin and his Chinese counterpart Xi Jinping were caught off-guard at a military parade in Beijing discussing the possibility of using biotechnology to pursue immortality.

In particular, Putin suggested repeated organ transplants could keep a person young forever.

There's a lot to unpack here. The idea of lifespan extension is less outlandish, and less objectionable, than it might seem. But as a bioethicist, I do have some concerns.

Putin's suggestion that we can achieve immortality via repeated organ transplants is almost certainly false.

One obvious question is where these organs would come from. Transplantable organs are a scarce medical resource. Using them to sustain the life of an ageing autocrat would deprive others of life-saving transplants.

However, Putin may have been envisaging lab-grown organs created using stem cells. This approach would not deprive others of transplants.
