Living to 150 years Possible?

Putin and Xi were talking recently on the possibility of human longevity up to 150 years, since they have no designated successors for the moment. There was also talk on Immortality in the next 40 years due to advances in Medicine and technology. 

Here's, a write-up on the possibility of these happening. 

Brainless bodies and pig organs: does science back up Putin and Xi's longevity claims?

The World's Most Notorious Leaders Claim They'll Live to 150. Is Immortality Closer Than We Think?

1. The Headlines: A Surreal Exchange

During a military parade in Beijing on September 3, 2025, a hot mic captured Xi and Putin casually discussing radical ideas: Xi mused that “70 years old is still a child,” while Putin replied that “with continuous organ transplants, people could live younger and younger and may even achieve immortality.” Xi chimed in: “Some predict that in this century, humans may live to 150 years old.” The GuardianPopular MechanicseuronewsTIME

Putin later confirmed the conversation to reporters, framing the discussion as reflecting hope in modern medicine and biotechnology's potential to vastly extend human life. The TimesCBS NewsThe Washington Post

2. What Do the Experts Say?

Organ Transplants ≠ Immortality

While organ replacement has advanced remarkably, experts caution that it’s not a silver bullet. UCL’s Prof. Reza Motallebzadeh notes organ transplants are complex, risky especially in older patients and can even reduce lifespan due to complications an immune suppression. The Guardian

José Viña, a physiology professor, argues that our cells including bones, muscles, and particularly the brain inevitably deteriorate. Simply swapping out organs like car parts grossly oversimplifies human biology. EL PAÍS English

Life-Span Limits Remain Elusive

The current verified record for human longevity stands with Jeanne Calment, who lived to 122 years and died in 1997. No one has surpassed that since, despite medical progress. EL PAÍS Englishwww.ndtv.com

Pinchas Cohen of USC states there is no evidence that humans will exceed 120 any time soon and suggests lifestyle, not miracle cures, remains the most reliable path to longevity. The Washington Post

Is Immortality on the Horizon?

Terms like “longevity escape velocity” when medical advances extend life expectancy faster than time passes are theorized but not yet realized. Notable futurists like Ray Kurzweil and Aubrey de Grey suggest we might reach such a point in the 2030s, though this is speculative. Harvard’s George Church gives a similar timeline mid-century maybe. Wikipedia

Progress in related fields such as organ bio printing, anti-aging gene therapies, and regenerative medicine shows promise but remains experimental. TIMEWikipedia+1

Russian-funded efforts like the 2045 Initiative even propose avatar-based immortality via mind uploading but critics note the roadmap feels more science fiction than imminent reality. Wikipedia

3. So, What’s Realistic?

Here’s a balanced breakdown:

Hope vs. Reality	Status Today
Organ transplant to reverse aging	Partially feasible, but risky and limited
Living to 150 years old	Highly unlikely based on current evidence
Achieving "immortality"	No credible path yet
Longevity escape velocity	Theoretical, yet unproven
Meaningful extensions of healthy lifespan	Reasonably plausible with ongoing research

The most defensible path to longer life today still involves well-established health measures balanced nutrition, exercise, stress management not replacing major organs or defying death outright. EL PAÍS EnglishThe Washington Post

4. Closing

For now, the dream of living to 150 or forever remains aspirational. Scientific breakthroughs may one day rewrite the story of aging, but for most of us, slowing the clock still starts with everyday health.

Finally, 

Your brain’s aging speed may predict disease, memory loss, and even how long you might live.

A new blood test can estimate how fast different organs in your body are aging, and researchers say your brain may be the most important one to watch. By measuring proteins in the blood and using AI to predict each organ’s “true” age, scientists found that people with biologically older brains were far more likely to develop Alzheimer’s and faced up to nearly double the risk of dying within 15 years.

 

The findings also showed that lifestyle habits like regular exercise, good sleep, and healthy eating could help keep organs especially the brain, biologically younger, potentially extending both lifespan and quality of life.

Meanwhile, 

Japan now has more than ninety five thousand centenarians, one of the highest concentrations of long living people in the world, and their habits reveal a powerful blueprint for healthy aging. Their diets are built around simple whole foods like fish, sea vegetables, fermented soy, green tea, and plenty of plants that nourish the body without overloading it. Meals are intentionally small because of the cultural practice of “hara hachi bu,” which means eating until you are eighty percent full. This reduces metabolic stress, balances weight naturally, and keeps inflammation low.

Daily movement is another key to their longevity. Older adults in Japan walk regularly, garden, stretch, and keep their bodies active through gentle everyday motions rather than intense workouts. This consistent but low stress activity supports strong muscles, better circulation, and a healthier heart. Community connection also plays a major role. Friendship circles, social rituals, and a strong sense of purpose help reduce loneliness and improve emotional well being, which directly supports longevity at the cellular level.

Many centenarians also drink antioxidant rich teas, prioritize sleep, manage stress through calm routines, and maintain mental sharpness through hobbies, curiosity, and lifelong learning. These simple habits work together to keep their bodies and minds resilient for decades longer.

Longevity is not an accident. It is a pattern of daily choices that support vitality from the inside out.
