Human immortality: Speculation upon Putin's discourse with Xi suggesting eternal life for humans.

In recent times, there has been a significant surge in investments aimed at extending human lifespan, a trend that has captured the attention of both the scientific community and the general public.

One of the key areas of focus in this quest for longevity is the field of epigenetics, which studies how genes can be toggled on or off without altering DNA. Research published in the journal Aging Cell in June found that the drug rapamycin, which appears to affect epigenetic ageing, has shown promising results in extending the lifespan of several animals, including mice.

However, while rapamycin has shown strong life-extending effects in various species even when administered later in life, its human use is limited by significant side effects. Mainstream scientists have been critical of such longevity efforts, warning they lack scientific rigor and could be dangerous.

The scientific community views drugs like Rapamycin, which affect epigenetic and aging pathways such as mTOR inhibition, as promising for extending lifespan based on studies in animals. Yet, while there is no conclusive evidence yet to confirm safe and effective lifespan extension in humans.

Eric Boulanger, a professor of biology and ageing at France's Lille University, shared his scepticism about the idea of regularly replacing organs to become younger, calling it "pure madness". His concerns echo those of many researchers who emphasise the need for a balanced approach to aging research, focusing on extending the number of years in good health rather than indefinite lifespan.

The Silicon Valley-led transhumanist movement, including billionaire Peter Thiel, has shown interest in longevity projects. Tech figure Bryan Johnson, who has set himself the goal of eternal life, is one such individual testing various anti-aging theories on himself.

Russia launched a 38-billion-ruble ($460-million) project last year focused on regenerative medicine and longevity. The project, a testament to the global interest in the field, was initiated by Russian President Vladimir Putin, who suggested that by regularly replacing misfiring organs people could actually become younger.

Despite the investments and research, it is important to note that there is no scientific evidence to support the idea that a human could live forever. Our bodies are made up of more than just organs, and the complexities of aging involve much more than simple organ replacement.

Jeanne Calment, who died at the age of 122 in 1997, holds the record for the oldest confirmed age. While this remarkable woman's case challenges our understanding of human lifespan, it does not provide evidence for the possibility of eternal life.

As the pursuit of longevity continues, it is crucial that we remain grounded in scientific fact and approach the subject with a balanced perspective. The focus should be on extending the number of years in good health, rather than seeking immortality.
