> damaged mitochondria Does that mean in all the cells or only some? Does this damage remain as cells die and get replaced by new ones? Is this damage encoded in the DNA or caused later by COVID? What I mainly mean is, is this damage getting replicated to new cells as your body generates new ones? AFAIK only DNA affects what new copies of cells will look like, so if it's only caused by COVID later on, what keeps this persistent?
