A number to orient yourself. Not a verdict.
The Longevity Score sums up a set of validated markers in a single index, to make it readable at a glance where you are and how you move over time. It is a compass, not a diagnosis.
What the Longevity Score is
It is a relative composite index: it combines several markers with solid evidence (cardiometabolic, fitness and strength, inflammatory) into a single summary score. "Relative" means it places you against a reference for your age band and sex, not on a universal absolute scale.
Its true value is over time: a single score says little, its trajectory — rising, falling, staying stable — says a lot. That's why the Score lives inside the re-test cycle, not in an isolated report.
Which markers compose it and why is explained on The science page.
How it looks
The Score comes with a visual picture — a "portrait" of your systems (heart, metabolism, fitness, composition, inflammation) — so you see not only the number, but where it comes from and where to act.
Illustrative example — values are not real. The dashboards shown serve only to illustrate the format; the numbers do not belong to a real person and do not represent results obtained. The interactive visualisation is in development (2026).
What the Longevity Score is not
- —It is not a diagnosis.It does not replace a physician's assessment nor identify a disease.
- —It is not a validated biological clock.It is not a certified biological-age test nor a recognised clinical endpoint.
- —It is not a guarantee.A better score does not promise a longer life; a worse score is not a sentence.
- —It is not a comparison between people.It serves to follow you over time, not to rank you against others.
- —It is not a "magic" number.It is a summary of real markers: it is worth as much as the data and the interpretation behind it.
Why reduce everything to a number?
Because a single number, used honestly, helps to communicate and motivate — provided you know what it represents. The Score adds no information to the markers that compose it: it summarises them.
For clinical decisions the individual values always matter, read by a physician in your context. The Score serves to hold the course, not to drive in the physician's place.
Longevity Score and Longevity Book
The Score is part of the Longevity Book, the document you receive at the first assessment: there you find the score, the markers that determine it, the priorities and the plan.
At every re-test, the Score and the Book update on real data — that's how the compass stays calibrated.
We build the Longevity Score with the same rule as everything else: to tell you what it means and what it does not mean. If one day you read a higher number, it will mean some markers have improved — not that we have "stopped ageing".
