Epigenetics and Aging
- Epigenetics, the study of gene expression changes, surpasses telomere length in predicting age.
- It explains how identical twins with the same DNA can develop different diseases and age differently.
The Epigenetic Clock
- Certain DNA sites predictably change methylation patterns as we age, creating an "epigenetic clock".
- This clock measures biological age, reflecting lifestyle choices and predicting lifespan better than chronological age.
Epigenetic Age Acceleration
- Epigenetic age acceleration, where your epigenetic clock is older than your actual age, signifies faster aging.
- Every five years of acceleration increases mortality risk by 8-15% and predicts health issues like cognitive decline and frailty.
