Someplace in Silicon Valley, a person wakes early with the dawn. Venturing into the kitchen, he pacifies his rumbling stomach with a cup of espresso infused with a big knob of grass-fed butter. He’s in the midst of a quick, in any case.
After a two-hour meditation session, he’s off to spend hundreds of dollars on his newest indulgence – stem cell injections. The clinic’s practitioner assures him that eradicating stem cells from his bone marrow and injecting them into different tissues will rejuvenate them from their fatigued state.
He trusts their phrase, simply as he trusts that spraying nicotine into his mouth will give him the advantages of a cigarette with out the destructive unwanted effects.
When he retires for the night time, outfitted with melatonin tablets and blue light-blocking glasses to make sure his sleep cycle isn’t disturbed, he’s glad with the day’s achievements. He’s taken one other small step in the direction of his aim. He could also be a product of the 21st century, however he’s additionally a part of the rising contingent who’re doing all the things of their energy to make it alive into the 23rd.
People have lengthy harbored an obsession with dwelling ceaselessly. However all those that shared the quest for immortality have one thing in widespread – they failed. And but the dream of eternity hasn’t wavered. A lot so, that many alive at present can’t assist however marvel if the important thing to their immortality is already lurking within the ever increasing pool of human information.
Trendy science has opened an assortment of latest methods to enhance survival, and now members of the technology-driven ultra-rich are adopting these new approaches in an try to increase their very own lives.
However what is usually left unsaid is that trendy science has additionally revealed the darker aspect of longevity extension: the inevitable physiological commerce offs that appear destined to carry us again. Nature appears set to disclaim our human varieties from having all of it. So what is going to it’s: humanity, or one thing else totally?
A utopian fantasy
Francis Bacon’s symbolic narrative New Atlantis was revealed in 1627. The unfinished novel portrays a society the place humankind has used science to wrestle management of its world from nature.
To some, this world represents a foreshadowing of the scientific utopia that we’re barreling in the direction of at the moment. However our world, in contrast to Bacon’s, is one filled with self-interest and greed, and it’s to those traits that the quest to defy getting older belongs.
Failed quests for immortality have an extended report. Within the Epic of Gilgamesh, considered one of humanity’s oldest tales courting again to the 22nd century BC, the title character embarks on an epic quest to achieve eternal life. After many trials and tribulations, he ultimately hears of a flower on the ocean flooring that may restore his youth.
And regardless of a warning from the one individuals ever granted immortality by the gods – that his quest will wreck the thrill of life – Gilgamesh plucks the flower from the watery depths.
His success doesn’t final. Gilgamesh inevitably loses the flower; and ultimately, like all mortals earlier than and after him, he dies. His is a narrative of defiance towards our mortal varieties, our endeavor to go to nice lengths to beat them, and the last word futility of the thought. It encompasses a theme that also holds vital relevance within the area of anti-aging analysis.

Almost 2,000 years later, the primary emperor of unified China, Qin Shi Huang, additionally discovered himself enamored with the thought of ruling perpetually.
He tasked his topics with discovering him the “Elixir of Life”, however as he aged with no reply in sight he started to develop determined. There’s proof that he started ingesting potions containing the extremely poisonous compound mercury sulphide. So in an ironic coincidence, his quest for everlasting life might have led him to a untimely grave.
Quick ahead to the 19th century and Elixirs of Life had made their approach into the mainstream, with many bars and apothecaries promoting their very own concoctions. Consisting of water, herbs and a substantial dose of alcohol, these potions, as soon as touted to increase life, have slowly morphed into in the present day’s natural cures.
However it will take one other 100 years earlier than society might fathom changing these elixirs with one thing based mostly on precise proof.
By the 1930s, scientists had used experiments on rats to disclose that proscribing energy might result in a big improve in lifespan, a discovering that also holds a variety of weight with in the present day’s immortality seekers. Regardless of this success, analysis into the processes of ageing remained small scale at greatest. However a revolution was on the horizon.
The yr 1945 noticed the delivery of the Gerontological Society, which established a journal and cultivated analysis curiosity within the fledgling area. Its work would show worthwhile, as by the early 1980s humanity’s understanding of and urge for food for growing older analysis had elevated significantly.

Proscribing energy was not the only merchandise on the listing of age-halting methods. New insights into how cells talk by way of signaling and the impression of this course of on cell conduct had swiftly come to the fore. Most notably have been these based mostly across the hormone insulin, which was discovered to manage many elements of ageing.
Then, in 1990, Daniel Rudman reworked the sector together with his research of the human progress hormone. He had observed that the quantity of lean physique mass (every little thing within the physique besides fats) decreased as the quantity of progress hormone produced by the physique’s cells waned.
Curious to see if he might reverse this development, his workforce injected older males with artificial progress hormones, reinvigorating their our bodies with a younger type by restoring their potential to interrupt down fats cells and develop new bone and muscle cells.
At this, entrepreneurs sat up and took discover. Many leapt on the thought for financial achieve, decided to promote the hormone as an anti-aging remedy. Journalists have been swept alongside within the wave of pleasure, writing of the “shot of youth” and asking if we might now cease getting older completely.
The metamorphosis of the anti-aging business had begun. And though nobody fairly knew what world would emerge when their longevity mission was finished, they have been decided that it might be one thing lovely.
The human progress hormone craze has since fallen away, however a heap of other supplementary therapies have readily taken its place. 2003 additionally noticed the completion of the Human Genome Venture, which was thought to carry solutions for fixing many age-related illnesses by figuring out the important thing genes that brought on them. But the reply to avoiding the deterioration that comes with age has remained elusive.
Within the years since, many analysis fields have been scoured seeking solutions: well being, sport science, psychology, drugs, pc science. Curiosity has solely intensified and rich benefactors have proven unrelenting perseverance, with whole corporations springing into existence in an effort to unlock eternity. Such confidence raises an inevitable query for the remainder of us: can it actually be carried out?
Biohacking the physique
There are numerous, many espresso outlets in California. However there are a number of, in downtown Los Angeles and Santa Monica for instance, that provide a singular expertise.
Inside, you’ll discover lighting that modifications all through the day, electromagnetic chairs designed to extend clients’ blood move, and espresso that’s infused with oil and served with butter. These are the entrepreneur Dave Asprey’s Bulletproof espresso homes, situated on the very coronary heart of the so-called biohacking motion.
Asprey is a well known, controversial determine who typically publicly claims that he’ll stay to 180 years previous by augmenting his every day habits to change his physiology. Asprey’s Bulletproof weblog is suffering from articles and podcasts detailing the well being advantages one can supposedly obtain by using such “hacks”.

These embrace dietary dietary supplements – which the cynical will word can be found as Bulletproof merchandise – and actions that topic the physique to emphasize.
We see a few of these debatable rules materializing within the Bulletproof espresso outlets, with Bulletproof espresso enjoying the star position however magnetic furnishings, grounded flooring panels and elevated yoga spots offering a various supporting ensemble.
Removed from being a precise science, biohacking is an umbrella time period that encompasses a bunch of self-help materials, a dollop of scientific reasoning, and a sprinkle of philosophy for good measure. (Individuals who make use of know-how to reinforce their our bodies have additionally been known as biohackers, however they’re extra generally known as transhumanists, which we’ll come to later).
A number of the extra eccentric biohackers even encourage common use of prescription and unlawful medicine, such because the psychoactive narcotic MDMA to enhance charisma and the narcolepsy nootropic modafinil to reinforce cognitive perform.
And in contrast to lots of Silicon Valley’s anti-aging corporations, which pay appreciable credence in the direction of genetic variation enjoying a key position in getting old, biohacking adopts a purely epigenetic strategy. It preaches that we will obtain longevity just by altering our habits and way of life.

So what kind of bodily stressors do biohackers advocate we topic ourselves to? There are numerous, however a superb instance is the widespread biohack of taking chilly showers.
Allegedly, soaking your physique in ice chilly water supplies a boon to the immune system. The scientific proof supporting that is tentative at greatest, and highlights the tendency of biohackers to readily extrapolate on scientific findings that reinforce their world view. However you solely have to scratch beneath the floor to uncover the murky water beneath.
The chilly might properly practice your blood vessels to be responsive, activate calorie-burning brown fats and lower irritation, however it’s a double-edged sword. Low temperatures can even constrict your blood vessels – growing blood strain – and improve your susceptibility to an infection. This acts as a counter to the supposed (and unconfirmed) well being boon.
With this in thoughts, chilly showers and different excessive practices – which Dave Asprey thinks will assist him stay to 180 years previous – are an adolescent’s recreation, and may fly within the face of extended life. A biohacking apply might yield a internet achieve in well being once you’re younger, however as you age there’s a very good probability the stability will shift in the direction of a loss.
Inevitability of trade-offs
The biohacking subject not often considers the darkish aspect of longevity extension, that each achieve comes with a commerce off. Analysis has proven that we will prolong life, however at a price in means to battle an infection.
For instance, we will prolong the lifetime of the fruit fly, Drosophila melanogaster, by forcing them to eat excessive sugar, low protein diets. This comes at a price within the type of fewer offspring per dad or mum and a lowered potential to battle an infection, a course of that requires protein.
We will additionally improve longevity by flattening immune genes or by exposing flies to a lifeless an infection. However, likewise, each of those remedies result in a considerably lowered capability to battle stay infections.
Zooming in on mobile elements reveals the molecular particulars underlying many such commerce offs. The Cinderella story of the anti-aging subject is mTOR (mammalian goal of rapamycin), a molecule that performs a various vary of roles sending alerts across the physique.
Controlling mTOR in impact permits us to regulate a lot of the cell system, together with the way it ages and divides. And there at the moment are a raft of anti-aging medicine that modulate the exercise of mTOR.
Biohackers, for their half, have cracked a method to naturally manipulate mTOR into an identical state by proscribing their calorie consumption, typically by way of intermittent fasting.
The logic behind this being that mTOR solely alerts the cell to construct and develop when there are sufficient vitamins round for it to be worthwhile. So consuming much less meals means much less mTOR exercise, decreasing cell progress and, in flip, the speed of cell dying. However proof exhibits that inhibiting this essential molecule’s perform not solely slows ageing but in addition suppresses the immune system.
Suppressing the immune system protects our mitochondria (Credit score: Raj Creationzs/Shutterstock)
Our immune system is expensive as a result of it makes use of our valuable mitochondria (the batteries that energy our cells) to supply poisonous compounds and trigger irritation when preventing germs, which damages the mitochondria. So by suppressing the immune system – as proven in each in our personal work and elsewhere – we will keep away from this type of injury and make it potential to extend longevity.
In fact, this strategy comes with appreciable danger. These experimental research have all taken place in managed environments with minimal publicity to germs.
In a pure surroundings, intentionally impairing an immune system, whether or not by way of drug supplementing or caloric restriction, can value us dearly, particularly in a world the place micro organism are persistently evolving extra resistance to antibiotics.
The commerce off between immunity and longevity is a wonderful instance of nature’s approach of balancing the scales. Stopping mitochondrial injury and suspending cell demise might look like wonderful life-extending practices on their face, however foregoing a totally useful immune response to get there’s a heavy, and probably deadly, worth to pay.
It’s additionally value noting that pure choice has conserved the mTOR-equivalent mechanism all through the evolution of all animal, fungal, and plants, which highlights simply how helpful it have to be. Maybe we shouldn’t be so able to tamper with such an integral factor to the health of our cells.
Immortality or humanity?
There’ll all the time be a myriad of the way our mortal varieties can go incorrect. And we’ve seen that physiological constraints appear set to all the time maintain us again from drastically extending our lifespans and remedying the basis explanation for growing older – if there even is one.
However on the border between science fiction and pioneering science relaxation thrilling technological concepts that would maybe unlock a special type of immortality. Know-how can already assist us catch age-related defects early, however it holds the potential to turn out to be even higher: what if we have been capable of circumvent organic commerce offs completely?
Billionaire Elon Musk’s firm Neuralink is already on the march to set us down this transhumanist path. It envisages a future the place people are much more intimately related with their digital units than we’re as we speak. It invitations us to work in the direction of a brain-machine interface that might basically combine us with our know-how, attaining a very symbiotic relationship.
The analysis continues to be in its early levels, however brain-machine interfaces are already in use within the type of ear and eye implants that may restore our senses, and mind implants that permit disabled individuals to remotely management computer systems and robots.
Neuralink goals to take this a step additional by seamlessly connecting us to digital units, the web and even different people. Primarily, we’d all have encyclopedic info available and have the ability to talk with each other telepathically.
To make this exceptional enhancement potential, a brain-machine interface can be injected into our bloodstream and journey to the mind. There it will self-assemble right into a mesh-like construction on the surface of the cerebral cortex, entwining know-how to the core of our intelligence and sentience.
Regardless of the invasiveness of Neuralink’s implants, there are already a number of wholesome people who’re keen for such synthetic enhancement. Some have even gone as far as to carry out surgical procedure on themselves simply to put in a gadget of meagre real-world worth. However this can be simply the beginning.
Neuralink and the know-how it evokes might turn out to be a gateway to a post-human future. By means of analysis on this space, we might decipher the means to precisely translate our natural, chemical neuronal pathways into digital knowledge that would encapsulate them. And so we might, ultimately, have the ability to seize our beings inside a pc, dwelling ceaselessly as digital reminiscence accessed by a bit of software program.
This may be an excessive answer to the query of the right way to reside ceaselessly, however there are rich people, reminiscent of entrepreneur Dmitry Itskov, dedicated to the thought of merging with a pc. Itskov’s 2045 Initiative views brain-machine interfaces as simply step one in a four-part journey that culminates in a man-made mind housing a human character that controls a hologram-like avatar.
Itskov and different futurists are promising immortality, however to achieve it we’ll should make probably the most important commerce off of all of them, freely giving one in every of our most valuable and defining presents: our human type. The natural mind has eternally been the vessel of our soul. A man-made copy might go so far as capturing your whole community of 100 trillion connections, however wouldn’t it really be you
It’s a deep query, however our transcendence (or simply divergence) away from natural matter signifies that we might properly stop to be human as we all know it. Considerations that people have been warring over for millennia – assets, wealth, mates – might stop to be essential. Bodily pleasures which were elementary to our expertise – intimacy, pleasure, music, meals – could be changed by digital alerts and artificial stimulants.
Or no less than for some. The remainder of us who can’t afford to develop into immortal avatars can be left to battle over these now trivial considerations, whereas the rich post-humans drift above for eternity.
Musk has proven that entrepreneurship can contribute to science via his forays into the area business and his firm’s revolutionary rocket design.
However the quest for longevity has been embraced so tightly by Silicon Valley and others within the enterprise world, that some scientific researchers have actively distanced themselves from tackling the difficulty. In a organic analysis subject that’s so reliant on a worldwide community of specialists, extra noble objectives have to take the outstanding place.
A elementary problem of all of those endeavors is that they’re an instance of science, presumably pushed not a lot by a want for higher understanding of the universe or the betterment of humanity, as by private revenue and particular person achieve.
Whether or not we’ll ever discover a method to overcome the physiological commerce offs that maintain again immortality, or whether or not we’ll actually be capable of replicate human consciousness in a pc are questions too troublesome for us but to reply. However are these main the cost towards dying no less than inspiring us to steer wholesome lives, or are they merely rallying towards an inevitable destiny?
In the event you have been to ask the rich patrons of Silicon Valley, the reply can be the previous. They’d direct you to the lifespan statistics, which have proven that we survive properly over a decade longer on common right now than we did simply 50 years in the past . They’d additionally emphasize the rising proof that defies the thought of an “upper limit” on how lengthy a person can survive.
Ongoing analysis, they’d argue, is already yielding fruit, and it’ll solely be exponential progress from right here. However, maybe sadly, our analysis has make clear the appreciable drawbacks in well being which will nicely come as a consequence of our meddling with anti-aging therapies. Man’s attain, it seems, continues to exceed his grasp.
