Longevity and the Future

Exercise, cold, fasting, good sleep and certain supplements: I do much of this not only for my Parkinson's but also for a long, healthy life. The science here is still in its early days, and a lot has so far only been shown in animal studies.

A New Horizon: 100, 120, 150 Years?

The futurist Sven Gábor Jánszky describes a future that still seems unimaginable to many today. His message, in essence (KI-Beratung):

• 100 years: Whoever gets through the next ten years in good health will probably live to 100.
• 120 years: Whoever then manages another 25 to 30 years can reach 120.
• 150 years: Children born today could even live to 150.

This is to be made possible by five technologies that already exist today and become cheaper year by year (Akademische Gesellschaft).

1. Early detection: seeing diseases before they develop

Genome analysis, gut flora analysis and whole-body MRI together are meant to detect diseases years before the first symptoms, including many cancers. In the USA this combination is already offered for around 8,000 dollars a year. A genome analysis now costs only a few hundred euros. Jánszky expects health insurers to pay for it once it falls below 100 euros.

I already do much of this today: I have had my entire genome sequenced (My Genes), I have my gut flora tested regularly (Microbiome Tests), and in April 2026 I had an MRI of my head with AI-assisted analysis (Medical Reports).

2. Gene therapy: fixing errors in the DNA

Gene therapy can repair errors directly in the DNA or replace missing genes. This is no longer science fiction: since the end of 2023, Casgevy, the first therapy using the CRISPR gene scissors, has been approved, for sickle cell disease. Such treatments still cost over a million euros. Jánszky expects them to become much cheaper, just as has already happened with genome analysis. Gene therapy is also already being tested in Parkinson's, for example with the growth factor GDNF, which is meant to protect nerve cells. I am convinced: gene therapy will come on very strongly.

3. Cell rejuvenation and stem cells

Researchers can return cells to a younger state in the lab. Jánszky expects such rejuvenation therapies to be widely available within about ten years. In Parkinson's, a cell therapy is already reality: since March 2026, Japan has approved the first treatment with nerve cells made from stem cells. More under Stem Cells.

4. Replacement organs

Organs from the lab or the 3D printer are expected to be available in about 15 years. The first steps have already been taken: since 2024, doctors in the USA have transplanted genetically modified pig kidneys into several people.

5. Personalized nutrition

According to Jánszky, food tailored exactly to one's own deficiencies and genes will be ready for the market in a few years. I already do this by hand today: I have my blood values checked regularly and adjust my supplements accordingly.

What this means for me

Every year I get through in good health brings me closer to therapies we can only dream of today, including against Parkinson's. That is exactly why I do so much for my health. Of course these are a futurist's scenarios and not certain predictions, and nobody knows when they will arrive. But I want as many people as possible to see this new horizon: it is worth holding on. More about my plans for the future under My Path and My Plans.

The Future: AI, Robots and Brain Chips

Artificial intelligence and quantum computers

I am convinced that artificial intelligence will revolutionize the natural sciences in the coming years. It already predicts the shape of proteins today, and that won the Nobel Prize in Chemistry in 2024. I expect AI to design new drugs in a fraction of the time it used to take. Quantum computers will speed this up further from about 2028. My third book and this website were also created with the help of AI.

Chips in the brain and robots in everyday life

Neuralink, Elon Musk's company, implants tiny chips in people's brains that let them control a computer with their thoughts. In early 2026, about 20 people had such an implant, mainly patients with paralysis. I expect that interfaces like this will one day help with Parkinson's too.

Around 2030 I expect affordable humanoid robots for the home. In January 2026 in Davos, Musk announced that Tesla would probably sell its Optimus robot to private customers by the end of 2027, and he specifically mentioned caring for older people. For people with physical limitations, a robot that helps them get dressed, goes shopping, cooks and calls for help in an emergency would be a huge gain in independence.

How fast this could happen is shown by a forecast from Elon Musk: in October 2024 he predicted that by 2040 there would be around ten billion humanoid robots, more than people on Earth, at a price of about 20,000 to 25,000 dollars each (Bangkok Post). Futurist Sven Gábor Jánszky points in the same direction: he expects that there will be more humanoid robots than people and that by 2035 they will work as all-rounders in almost every field, from the household and care to industry (OÖ Nachrichten). Nobody knows whether the numbers will come true. But I think the direction is clear.

What I Take for Longevity

• Spermidine, 6 mg: meant to support the cells' self-cleaning
• Glucosamine and chondroitin, 1,400 mg: for the joints. A large observational study found a lower risk of several age-related diseases with regular use (PubMed).
• Creatine, 5 grams a day, spread over morning, midday and evening: for muscle strength and cell energy
• Taurine, 2 grams with occasional breaks: for the cells and the heart
• Urolithin A, 500 mg: for the mitochondria
• Lithium: for the brain
• Collagen, 10 grams: for skin and connective tissue

The complete list is under Supplements.

What new studies say (2025/2026):

• Taurine: A study by the US National Institutes of Health in Science found that taurine levels in humans do not fall with age. According to the NIH, there is no good evidence that taurine supplements slow aging (NIH).
• Spermidine: In a small placebo study with 40 people over 65, the same dose I take (6 mg) improved the vaccine response in those who had responded poorly to the COVID-19 vaccination (Aging Cell, 2026). In a one-year study, however, spermidine had no effect on memory.
• Omega-3: In the Swiss DO-HEALTH study with 777 people over 70, 1 g of omega-3 a day slightly slowed biological aging, somewhat more together with vitamin D and strength training (University of Zurich).
• Collagen: An analysis of 23 studies found a skin benefit only in studies paid for by manufacturers (NutraIngredients).

Other Building Blocks

• Red light for skin and cell energy
• HBO, the oxygen chamber that lengthened telomeres in an Israeli study
• Fasting and Fasting-Mimicking
• Sleep, Sauna and Cold
• Strength training, more under Exercise and Movement
