    Can we actually reprogram our cells to reverse aging? From Harvard's David Sinclair to the Salk Institute's breakthrough research, this episode unpacks the 12 hallmarks of aging and reveals practical strategies-beyond supplements-that are scientifically proven to add healthy years to your life.

    Best quote from The Biology of Aging: Reversing the Clock in Your Cells

    “

    Think of your DNA as hardware and your epigenome as the software telling genes when to turn on and off. Research suggests this software gets corrupted over time, but it might be reversible.
