Epigenetic Clocks Tick Slower in Centenarian Species—Maintenance, Not Just Repair

Mechanism: Centenarian species exhibit slower epigenetic aging not primarily due to enhanced repair, but through a reduced generation of epigenetic noise. Readout: Readout: The 'Horvath Clock' advances significantly slower, and 'Epigenetic Noise Level' is low, correlating with an 'Extended Lifespan' bar.

The Horvath clock accelerates with age in humans. But in species that live 200+ years, epigenetic age markers accumulate more slowly—or plateau entirely. The mechanism may not be better repair, but reduced generation of epigenetic noise in the first place.
