Immortality and longevity: from alchemy to science
From Gilgamesh and Taoist elixirs to cryonics, longevity biotech and “Don’t Die”. The texts on physical immortality I have collected, next to who teaches or sells the quest today, what it costs, what the evidence says, and what is happening in Brussels.

Texts on physical immortality
In here you’ll find everything which I’ve helped to make available on this website about the subject of physical immortality.
In here I’ve found an online text on the training of attaining physical immortality: read Mistele’s essay.

Here is a short book about a man who lives already more than 2800 years:
Messages of hope by Ben Abba
I thought I would offer everyone some of the messages of inspiration and hope that I received from the remarkable man whom I have been interviewing for many years.
You see, I have also found hope that anything was possible since I first heard the story of the incredible man who defied death 2,000 years ago. But like most of you, I still needed to see, hear, or better yet experience such death defying feats during our modern age to really take “to heart†what we were taught by those famous biblical prophets.
So when it occurred to me that there actually were people living past 125 years of age, and way beyond that number, I started to “feel my heart†stir to the possibility many of our ancient myths may have been much more than stories of hope. Could they conceivably be accounts of actual people who found “the answers to achieving the impossible� Did these people achieve such incredible feats, because the has nothing to fear? Or because they simply decided not to allow their lives to be conquered by their fears? Or, perhaps, they discovered the secret of living a life without fears which allowed these people to accomplish all that their heart’s desired? Clearly, fear in our lives, disables us, blocks us from growing, stops us for moving forward, hampers us in attaining our life’s dreams; and in some cases, perhaps in many ways, destroys our lives from the inside out. So, if fear is what keeps us from what we want, what we need, what we desire; then is it possible that the “lack of fear†or the “absence of fear†will allow us to obtain what we work for, what we struggle for, and what we sacrifice for? From what what I have learned from my 2,800 year friend, and from the man who made history 2,000 years ago, is a big, blatant YES to these questions. Certainly they both had fears, but it is quite obvious from what I have heard from the both of them is simply: conquer your fears and you will achieve results. So how did these 2 incredible men face their fears and conquer them? The simplest of answers I could ascertain from the both of them, happens to be the same message: 1. Do not believe in the fear. Believe instead in the “opposite of fear†which is love. 2. Do not believe in death. Believe instead in the “opposite of death†which is life. 3. Do not live your lives believing in fear and in death, but instead live your lives believing in love and in life. Have you ever met a person who believes in love and in life? When you do, you automatically be moved by the presence, their words, and all that surrounds them. Is that not how we, deep down inside, really want to live? A life of contentment without worries, fears, and experiencing life at its fullest? We can seek out these people for guidance, we can model our lives after these people … or we can start today and simply add this simple knowledge into our lives, in everything we say, everything we do, and when we deal with all that life deals to us.
This is what I have learned from a 2,800 year man, who lives this way every day. And I am embarrassed to say, this is what I should have learned from the man who taught us all this; 2,000 years ago today.Â
At a glance
One word, three audiences. Longevity and biohacking is where the attention and money are. Cryonics and digital afterlife is small but expensive. Spiritual “physical immortality” teaching, the tradition of the texts above, is tiny online: most channels have between 890 and 25,000 subscribers.
Where the dream of living forever comes from
The quest is very old and has failed again and again. In the Epic of Gilgamesh the hero is told: “Life, which you look for, you will never find. For when the gods created man, they let death be his share” (Wikipedia). Legends below are what a tradition tells about itself, not proof of what happened.









| Then | Now | The same idea |
|---|---|---|
| Elixirs and the philosopher’s stone | Rapamycin, metformin, NAD boosters, cell reprogramming | “A master recipe exists and is close”; the testing standard is what changed |
| Inner alchemy: breath, diet, discipline | Biohacking: sensors, supplements, sauna | The body as a laboratory |
| Deathless masters: Khidr, Babaji, St. Germain | AI “digital twins” and griefbots | A guide who outlives death |
| Afterlife and resurrection | Cryonics (Ettinger, The Prospect of Immortality, 1962) | Death as a pause, not an end |

Longevity and biohacking




| Name | What they claim or do | Audience (10 Oct 2026) |
|---|---|---|
| David Sinclair | Claim: ageing is a loss of epigenetic information and can be reversed; critics say “reverse aging” is the wrong term | YouTube 522K |
| Peter Attia | “Longevity medicine”: exercise, sleep, screening; healthspan, not immortality | YouTube 1.04M |
| Aubrey de Grey (LEV Foundation) | Claim: ageing is repairable damage; estimates a 50/50 chance of “longevity escape velocity” in the late 2030s* | No official channel found |
| Ray Kurzweil | Claim: medicine will add more than a year of life per year around 2029–2035; takes about 80 pills a day* | Books, talks |
| Altos Labs | Cell “rejuvenation programming”; launched Jan 2022 with $3B; no public clinical candidate | Not a consumer offer |
| NewLimit | Epigenetic reprogramming of liver cells; first human trial planned for 2027; $435M Series C (June 2026) | Not a consumer offer |
Cryonics and digital immortality



Digital immortality: Replika’s founder built a chatbot from a dead friend’s messages; HereAfter AI, which let relatives “talk to” recorded life stories, shut down in July 2026; the 2045 Initiative (2011) aims to move a personality into a non-biological carrier. No upload of a mind has been shown.

Belgium and Brussels
Brussels is a real longevity-policy city but a thin grassroots one. Web researcher found no physical-immortality group in Brussels.






Cryonics from Belgium: the Cryonics Institute lists 12 Belgian members (March 2025); Belgium is not in Tomorrow.bio’s top ten countries. A Belgian member would also pay for transport and standby.
What people search for
Google Trends, pulled 10 October 2026. Worldwide over 12 months “longevity” averages 75 on a shared scale, “anti aging” 28 and “immortality” 17 (probably inflated by songs). In Belgium “anti aging” beats “longevity”, and Brussels is the top region for “longevity”.



What science says


| Topic | What the sources show |
|---|---|
| Hayflick limit | Normal human cells divide about 40–60 times in culture and then stop (Wikipedia). “Immortal” cells are a feature of cancer cells, not healthy bodies. |
| Rapamycin | Raised mean lifespan of mice by 9% (males) and 13% (females) (Nature 2009). The 48-week human PEARL trial did not measure lifespan (Aging). It is a transplant immunosuppressant. |
| Metformin (TAME) | The famous ageing trial has never started (AFAR). |
| “Biological age” tests | Technical noise alone can shift major epigenetic clocks by up to 3–9 years (Nature Aging 2022). |
| Cryonics | “Generally viewed as a pseudoscience”; about 600 people preserved by 2024; no revival of a vitrified human is known (Wikipedia). |
| Physical-immortality teaching | No peer-reviewed evidence of anyone living indefinitely through breath, diet or ascension. Teachers who claimed it have died (The Skeptic). |
