Episode Description
We follow the trail from DNA methylation to epigenetic clocks that can read biological age like a personalized receipt of your life. Then we hit the hard limits of today’s tests, especially the gap between predicting lifespan and predicting whether your brain stays sharp.
• DNA methylation as gene control through steric hindrance and chromatin tightening
• Epigenetic clocks built from predictable CpG changes over time
• Why first-generation clocks track birthdays more than health
• PhenoAge and GrimAge as decay predictors tied to inflammation and smoking damage
• French centenarian data showing biological ages decades younger
• Epigenetic drift versus clock-like methylation changes and what superagers reveal
• ELOVL2 and mouse evidence that some aging is reversible gene silencing
• WIMS findings showing blood clocks predict survival not dementia risk
• APOE E2 E3 E4 risk differences and epigenetic “volume dial” control
• FOXO3 activation through fasting via IGF-1 and AKT signaling
• Metformin and rapamycin as fasting mimetics plus the mouse-to-primate reality check
Keep your biological software updated, embrace a little bit of hunger, stay curious, and we'll see you next time.
