: '''The 'Hayflick' Discovery (1961)''' → The first proof that "Cells are not immortal"—they have a "Built-in timer" for death.
: '''Telomerase (Elizabeth Blackburn)''' → The discovery of an "Enzyme" that can "Add pages back" to the telomeres, winning the Nobel Prize and giving hope for "Reversing" the clock.
: '''Senolytics''' → A new class of drugs that "Specifically Kill" only "Senescent Cells," leaving healthy cells alone. In "Mice," these drugs made old mice "Younger, Stronger, and Faster" again.
: '''The 'Hallmarks of Aging' (2013)''' → The "Master List" of the 9 biological reasons why we age, which gave scientists a "Map" of where to focus their research.
