How Close Are We To Immortality And Eternal Youth?

Updated: Aug 16, 2023

A Scientific Perspective

The Longevity of Legends

From Methuselah to Merlin, immortality has captivated the human imagination for millennia. Once the pursuit of alchemists through the Philosopher’s Stone, the 21st century’s burgeoning biotechnologies are breathing new life into our quest for eternal youth. In this context, we explore the biological, social, and philosophical aspects of extending human life.

A Cellular Perspective: The Role of Telomeres

Ageing is far from simple. It is a complex interaction of genetics, lifestyle, and environment. One prime suspect in the ageing process is ‘telomere attrition’. As cells divide, telomeres – the protective caps on our chromosomes – shorten. Telomerase, an enzyme, can rebuild these caps and has been shown to extend lifespans in mice. But what ethical questions would human implementation raise? Might we see a divide between those who can afford such treatment and those who cannot?

The Old Blood Problem: Parabiosis and its Implications

Experiments on mice hint that a factor in old blood might accelerate ageing. Youngblood transfusions seemingly rejuvenate older mice, prompting the launch of human clinical trials and controversial businesses. However, this 'vampire' treatment is no magic bullet, with risks and ethical concerns casting a dark shadow over such procedures. Critics argue that the science is still too nascent and the risks too poorly understood.

Engineering Youth: Organ Regeneration and 3D Printing

Our organs wear down as we age, becoming a primary cause of elderly mortality. Breakthroughs in regenerative medicine, such as stem-cell-derived organ printing, may soon let us replace our worn-out parts as easily as one might replace a car’s ageing transmission. But how would society handle supply and demand? Would we create a new set of organs for every individual, or would this privilege be reserved for a select few?

The Miracle of Exosomes in Skincare

Enter exosome therapy. A darling of dermatology, exosomes are cellular messengers. Extracted from stem cells, these nanoparticles prompt skin cells to rejuvenate, healing damage and reducing signs of ageing. The treatment has found particular success in the Korean beauty industry, offering clients glowing, youthful skin. Yet, as this technology is still in its infancy, long-term effects and potential risks remain largely unknown.

The Socio-Economic Impact of Living Longer

Longevity treatments, when they arrive, will likely be the preserve of the wealthy elite initially. A class of eternally young CEOs and politicians could ossify societal structures, resisting change that threatens their status quo. Over time, as these treatments become more accessible, the world must face potential overpopulation, raising profound ethical questions.

Intergenerational Relations in an Immortal Society

With lifespans extending into centuries, familial structures may shift dramatically. If five generations are alive at the same time, what will this mean for inheritance, housing, and family dynamics? How would relationships change if “till death do us part” no longer applies?

The Psychological Toll of Eternal Life

Living for centuries is likely to bring about unforeseen psychological challenges. The potential for multiple lifetimes worth of memories raises questions about mental health in an extended life. Would we experience increased rates of mental illness, or would our minds adapt to accommodate this new longevity?

The Future Society: A Philosophical Perspective

When longevity becomes widespread, society must confront uncomfortable realities. Will there be criteria to meet for access to life-extending therapies? Might you need to create great art, contribute to science, or achieve a level of societal status by a certain age to qualify?

In Conclusion: A Dream or a Nightmare?

Immortality, while seemingly within our scientific reach, brings with it an array of complex questions that extend beyond the scope of science into the realm of ethics, philosophy, and societal structure. The first immortals are likely to be among us soon. But as they step into their new, elongated lives, will they be embarking on a dream or entering a new kind of nightmare? The true challenge of immortality may lie not in achieving it, but in living with it.
