During one of the world’s most spectacular military parades in Beijing, a forgotten live microphone captured a strange exchange. Russian President Vladimir Putin and Chinese leader Xi Jinping were overheard pondering the possibility of immortality, suggesting that the key might lie in organ transplants.

Putin and Xi talk immortality

According to a report by The Guardian, as the two leaders strolled across Tiananmen Square during the parade showcasing nuclear weapons and military hardware, Putin’s interpreter was heard saying: “Human organs can be continuously transplanted. The longer you live, the younger you become, and [you can] even achieve immortality.” Xi responded by noting that some believe humans could live up to 150 years in this century.

The topic is no coincidence for the two authoritarian figures: both have amended their constitutions to stay in power for life. Only biological limits stand in their way.

What does science say?

According to IFLScience, while the idea sounds intriguing at first glance, it’s far from feasible in practice. Though there are ongoing efforts to continually replace organs, the concept faces major obstacles.

First, there’s already a significant shortage of donor organs. In reality, it’s not just dictators who struggle to access transplants: many critically ill people don’t receive life-saving organs in time. Second, xenotransplantation (transplanting animal organs into humans) is still in its infancy. While a few patients have received genetically modified pig hearts or kidneys, most survived only a few months after surgery.

Many scientists see the key to longevity in genetic rejuvenation. A group of genes known as Yamanaka factors can “rewind” ageing cells to a stem cell-like state, effectively rejuvenating them. However, this research is still in an early phase and far from offering immortality to anyone.

The limits of reality

The longest confirmed human lifespan belongs to Jeanne Calment, who lived to be 122. Many consider this the natural limit for human organs, making the dream of living to 150 years highly uncertain.

Experts argue that healthier ways to extend life include proper nutrition, regular exercise, and avoiding smoking: all of which have been scientifically proven to increase lifespan. Some experiments also suggest that certain psychedelics, like magic mushrooms or low doses of cannabis, may slow the ageing process.

So while Putin and Xi may dream of immortality in the shadows of the parade, current science suggests they’re far more likely to gain a few extra years than eternal life.
