Aging is basically a process that happens to inanimate objects like cars, and it also happens to us, despite the fact that we have a lot of clever self-repair mechanisms, because those self-repair mechanisms are not perfect.
Plakja eshte nje proces qe ndodh tek objektet e pajete, si makinat, dhe gjithashtu ndodh tek ne, pavarsisht nga fakti se ne kemi shum mekanizma te zgjuar vete-riparimi, per shkak se keto mekanizma vete-riparimi nuk jane perfekte.
