Measured, not remembered
Health data
I entered the Longevity World Cup, an open competition that ranks people by how far a biological-age clock puts them under their real age. Mine puts me 2.8 years over it. Everything here carries a date, and anything I have not measured says TBD.

How the number is calculated
Pheno Age is a regression from Levine et al., 2018, fitted to mortality data. It takes nine blood values plus chronological age and returns a number in years. Above your real age means the panel looks like an older person’s; below means younger.
It knows nothing about me that is not in those nine values, and it cannot tell the difference between aging and having a bad night.
Pace of aging is 1.11 years per year. The site computes my acceleration against a chronological age carried to a decimal, which is why it reads +2.8 rather than the +3.0 you get from 29.0 minus 26.

The nine markers
| Marker | Value | Unit | Reference |
|---|---|---|---|
| Albumin | 43 | g/L | 36–48 |
| ALP | 61 | U/L | 35–105 |
| Creatinine | 86 | µmol/L | 60–105 |
| CRP Censored on the report. The clock needs a number, so it went in at the bottom. | <1 | mg/L | <5 |
| Glucose Non-fasting, against a fasting interval. | 5.2 | mmol/L | 4.0–6.0 |
| Lymphocytes derived 1.2 ÷ 10.9. The report gives counts, the clock wants a percentage. | 11.0 below range | % | 20–45 |
| MCV | 94 | fL | 82–98 |
| RDW | 13.0 | % | 11.5–14.5 |
| WBC | 10.9 above range | 10³ cells/µL | 3.5–10.0 |
What is moving the number
- White cell count 10.9 → 6.0−3.0 years
- Lymphocytes 11.0% → 30%−2.5 years
- Both at once−5.5 years
Not a hidden better score. A raised white count with a flat CRP is a body under acute stress, which is what the clock is reading. This entry is a bad baseline rather than a bad result, and the fix is another draw on an ordinary day.
