Longevity Score.
The six pillars of longevity: scored and weighted. Find out where you're thriving and where you're leaving healthspan on the table.
Frequently Asked Questions
What does the longevity score actually measure?+
It scores your current habits across six evidence-based pillars (sleep, nutrition, movement, strength, stress and substances) and returns a single 0 to 100 number. It is an audit of behaviour, not a measurement of your body, so it reflects what you are doing now rather than what has already happened to you.
Is this the same as a biological age calculator?+
No, and the difference matters. A biological age calculator estimates how old your body appears; this scores the inputs that shape that outcome. The score is the more actionable of the two, because every point is attached to something you can change this week.
What is a good score?+
The score is most useful read as a distribution across the six pillars rather than as one number. Someone at 70 with all pillars even is in a very different position from someone at 70 carrying one pillar at rock bottom, and the second person has the far bigger opportunity, which is why the result names your weakest pillar rather than only handing you the total.
Can it tell me how long I will live?+
No. Nothing can, and any tool claiming otherwise is guessing. What the underlying research supports is that these six behaviours are consistently associated with healthspan (the years lived in good health) across large populations. That is a statement about groups, not a forecast for an individual.
Why these six pillars and not others?+
Because they are the levers with the largest and most repeatedly replicated effects in the longevity literature, and because each is modifiable. Genetics matters enormously and appears nowhere in the score, for the simple reason that you cannot act on it.
How often should I retake it?+
Quarterly is about right. The behaviours it measures move over weeks and months, not days, so retaking it more often mostly measures noise and how you happened to feel that morning.
What this score actually estimates.
This is a six-pillar lifestyle audit, not a biomarker-based clock. The pillars (sleep, nutrition, movement, stress, social connection, and sense of purpose) were chosen because each has independent, well-replicated associations with all-cause mortality and healthspan. The score is a fast, free screen of which pillar is dragging your risk profile.
The headline number to keep in mind: Li et al. (2018, Circulation) tracked over 120,000 adults for up to three decades and found that adopting five low-risk lifestyle factors (never smoking, healthy BMI, ≥30 min daily activity, moderate or no alcohol, healthy diet) added ~12 years of life expectancy for women and ~14 for men compared with adopting none. Lifestyle is dose-responsive across this entire distribution.
Why the non-physical pillars are weighted heavily.
Social isolation and weak social ties carry mortality risk on the order of smoking 15 cigarettes a day: Holt-Lunstad’s 2010 meta-analysis of 148 prospective studies found a 50% increased likelihood of survival for people with stronger social relationships. Most longevity programs under-weight this because it is harder to prescribe than a protein target.
Sense of purpose is similarly load-bearing: Cohen et al. (2016) and the English Longitudinal Study of Ageing both showed that a higher purpose score predicted lower all-cause mortality independent of physical health, depression, and income. The mechanism is partly behavioral (people with purpose adhere to health behaviors better) and partly biological (lower cortisol, better inflammatory profile).
How to use your result.
The pillar with the lowest score is your highest-yield intervention, not the one you find most interesting. If sleep scored a 4 and you spend your free hours optimizing supplements, you are leaving the largest available gain on the table. Fix the worst pillar first; the others tend to improve secondarily because sleep, stress, and movement are tightly coupled.
Treat this score as a screening tool, not a diagnosis. For an objective companion metric, pair it with a biological age estimator and an annual lipid + HbA1c + ApoB + hs-CRP panel. The score tells you what to change; the bloodwork tells you whether the changes worked.

Your weakest pillar is the priority. The bundle has the training, nutrition, and recovery protocols to move it.
