But you are always fighting a losing battle with the clock and eventually you die from the death of a thousand cuts.
Epigenetics involves strategies to slow and even reverse this damage.
One mechanism of DNA repair is DNA polymerase which are these little biological error checking machines that travel up and down your DNA strands and repair mutations.
Another way to reduce genetic mutations is through the administration of telomere lengthening drugs and plants based compounds. This should slow ageing.
It's a big new field but that's one of the main research ideas.
