query: What is the DNA damage theory of aging?
answer: The DNA damage theory of aging proposes that aging is a consequence of the accumulation of unrepaired, naturally occurring DNA damage. This damage can lead to cell dysfunction, apoptosis, or cellular senescence, contributing to the aging process.  Deficient DNA repair accelerates aging, while increased repair is linked to longer lifespans.
