Aging can be defined from a molecular perspective, focusing on damage accumulation and its consequences, such as mitochondrial dysfunction and telomere shortening.

“I think um in the past i often gravitated towards sort of a molecular definition of aging so you know what are the types of damage that occur during aging what are the consequences of that damage um sort of a you know in some ways a hallmarks of aging framework view right where we we know that things like mitochondrial dysfunction telomere shortening uh cellular senescence things like that happen during aging at the cellular and molecular level and contribute to many of the functional declines and diseases that go along with aging”
