Live for 150 Years?

Seven out of ten deaths in the Western world are caused by diseases we could largely prevent. Heart attacks. Type 2 diabetes. Cancer diseases. Chronic respiratory illnesses. Strokes. These are not acts of fate. They are consequences of how we eat, move, sleep, and manage stress — compounded over decades, enabled by a healthcare system that intervenes only after the damage is done.

I trained as a physician at Karolinska Institute, one of Europe's leading medical universities. I learned to treat disease with extraordinary precision. What I was not taught — what almost no medical school teaches well — is how to prevent it. Your car gets an annual inspection by law. Your body — the only machine you cannot replace — gets attention when it breaks down. I could not accept that. So I built what I was missing: one of the world's first longevity clinics, dedicated not to treating disease but to preventing it.

From treating breakdown to preventing it

Modern medicine is reactive by design. We wait for symptoms. We diagnose. We treat. In many cases, we do this brilliantly — surgical interventions, immunotherapies, and emergency care have reached a level previous generations could not have imagined. But the model has a blind spot: by the time a patient shows up with a diagnosis, the biological process that caused it has often been running for ten or twenty years.

In 2009, I founded SciLife Clinic — one of the first preventive longevity clinics in the world. The idea was radical at the time: what if medicine started before disease? What if we used advanced biomarkers, genomics, imaging and metabolic profiling not to diagnose but to predict — and intervene while the body is still healthy?

What I experienced in the clinic confirmed what the research had been saying for years. Early detection saves lives. In addition, people who understand their biology make different life choices. Not because they are scared, but because they are informed. A patient who sees their own inflammatory markers trending upward does not need a lecture about diet. They need a plan. They need the doctor, as a partner to their health.

The frontier

Longevity science has moved from the fringes to the frontier. Senolytics — drugs that clear damaged cells — are in clinical trials. Epigenetic clocks can measure biological age with remarkable accuracy. Rapamycin analogs are being studied for their ability to slow aging at the cellular level. CRISPR gene editing opens the possibility of correcting inherited disease risks before they manifest.

Artificial intelligence is accelerating every part of this. AI-driven drug discovery is compressing timelines that used to take a decade into months. Machine learning is making early diagnosis more accurate than any individual physician. Natural language models are synthesizing research at a scale that no human team could match.

For the last two decades, I have pushed for a paradigm shift towards a preventative approach towards a future of health where genomics, AI and precision medicine are at the core of healthcare. Working in the intersection of these fields, being the pioneers within longevity, I have been asking the same question ever since I founded SciLife Clinic: how do we give people more time — not just more years, but more healthy, functional, meaningful years?

The existential question

But here is what most longevity conversations miss. If we live to 150 or beyond — and the science suggests we may — we will need entirely new definitions of purpose, career, family, and identity. A life that spans several careers, possibly multiple partnerships, and decades of post-retirement existence is not just a longer version of the life we know. It is a fundamentally different kind of life.

The challenge of longevity is not biological. It is existential. The science of living longer is advancing faster than our ability to answer the question: what is all that extra time for?

That is the question I keep coming back to — not as a scientist looking at data, but as a human being who was clinically dead at three and has spent every day since then trying to understand what it means to be alive.
