Why Your Biological Age Matters More Than Your Birthday
Dr. Anjali MehraMay 20, 2026
The 20-year gap
Two 45-year-olds walk into a clinic. One has a biological age of 38; the other, 56. Same birthday, eighteen-year gap in cellular wear.
This isn't hypothetical. Epigenetic age tests like DunedinPACE and GrimAge now reliably measure how fast your cells are ageing — independent of the calendar.
What we measure
- DNA methylation across 100,000+ CpG sites
- Pace of aging — how many biological years pass per chronological year
- Tissue-specific clocks for heart, brain, liver
What you can change
The single most impactful intervention we've seen in our cohort: sleep optimisation, followed by zone-2 cardio and resistance training. Pharmacological interventions (rapamycin, metformin) come later — and only after the foundation is solid.
