The cells in our body are constantly replicating themselves. During the replication process, DNA is copied and pasted for the new cell. The copying and pasting process doesn’t always go right and sometimes you run into mutations. Aging is a part of this DNA mutation phenomenon. As more things go wrong, your body slows down and becomes weaker. This along with all the physical stress your body goes through on its life.

So it's impossible to halt this process, as we would need to correct every single cromossome. Am I correct?

However if that is true then why the son from a man in his 60s doesn't borns old? Better, how didn't we start to degenerate after the few generations from the first living being, as DNA is always mutating.

Pardon from my ignorance If I talked something wrong.

DNA mutations aren’t always a bad thing. Sometimes mutations can offer benefits. Think about evolution. Species evolve thru genetic mutation over generations and generations.
