Some longevity researchers could investigate the DNA sequence of the mitochondrial DNA(a discrete object) to see if there is a length of life correlation = CRISPR edit towards longer life. It would be easily explored in mice and then there could be some edits in an egg very soon after fertilisation to replace that mitochondrial DNA in that egg to see the result. Might be a hard task to find/replace all these mitochondria and maintain life? In a single mouse egg = how many are there? A search finds this interesting paper = a good rabbit hole indeed. It is an area of intense research. https://pmc.ncbi.nlm.nih.gov/articles/PMC4684129/
