Why do you do that? Why would you think it is correct?
To my knowledge that's a wrong interpretation.
Yes there is constant continuous damage to DNA and cells etc. But the body has mechanisms to repair that damage. It is the repairment that slows down during aging, and that is programmed by genetic and biological processes, like everything else in the body. Biologically, a cell can keep reproducing over and over again, it is no problem.
- dnhz 7y agoPut it simply, there is reversible damage and irreversible damage. Oxidized protein aggregates that the cell can’t degrade are an example of irreversible aggregates. Amyloid protein fibrils, although no longer implicated in disease, are another example of a stable, irreversible state. The process of repair slows down not due to programming but because the cells of the body get progressively worse at identifying and repairing damage, because the very machinery that carries out these processes, proteins, get damaged.
