Two Ages, One Body
Chronological age is the number of years since birth — non-negotiable. Biological age reflects how well your cells and tissues are actually functioning. Two 50-year-olds can have biological ages that differ by 10–20 years — one ageing at an accelerated pace toward chronic disease, the other ageing slowly with preserved function.
How Biological Age Is Measured
The most advanced tool for measuring biological age is the epigenetic clock. It analyses DNA methylation patterns — chemical tags on your DNA that change predictably with age and lifestyle. Specific methylation sites act as a molecular timestamp, and machine learning models trained on thousands of samples predict biological age with remarkable accuracy.
You do not have a single biological age. You have many — one for each organ system. The goal is not just to live longer. It is to compress morbidity into the shortest possible period at the very end of life.
What Accelerates Biological Ageing?
Insulin resistance and chronic hyperglycaemia — glucose directly accelerates epigenetic ageing through advanced glycation end-products (AGEs)
Chronic inflammation — sustained elevation of inflammatory cytokines drives cellular senescence
Oxidative stress — excess reactive oxygen species damage DNA and accelerate methylation drift
Poor sleep — even partial sleep deprivation accelerates epigenetic ageing
Psychosocial stress — chronic stress shortens telomeres and accelerates the epigenetic clock
Environmental toxins — PFAS, heavy metals, and air pollution directly impact methylation patterns
Slowing — and Even Reversing — Biological Age
Address insulin resistance — normalising glucose and insulin is one of the most powerful anti-ageing interventions
Prioritise sleep — consistent, high-quality sleep slows epigenetic ageing more than most supplements
Time-restricted eating and caloric optimisation — triggers autophagy, the cellular clean-up process
