It’s both. As when you use a copier and make a copy of a copy of a copy and it starts to fade and small imperfections begin to be magnified, your DNA makes [copies](https://genetics.thetech.org/original_news/news91) of itself over time and this too begins to happen. Small imperfections become magnified over time and issues from cancer, to improper DNA methylation, and [telomere](https://pubmed.ncbi.nlm.nih.gov/17943234/) disregulation can occur all leading to a higher mortality rates.
