What's the current thinking on how to prevent physiological decay over time (id est ageing)? Figure a way to recover the bits of DNA cleaved in mitosis?
Shortening telomeres are a red herring. You need multiple generations of a mammal not having telomerase before you get premature ageing, and all the research you've heard about where they 'reversed ageing' with telomerase was putting it back into animals that had been engineered to lack it for generations. Plus lack of telomerase in most of your somatic cells is one of your big anti-cancer defenses.
Much more of a problem is things like nuclear pores never being replaced in post-mitotic cells (they're only replaced during mitosis) and slowly oxidizing and...
