I've also had this idea -- I wonder if it's chance or if this is something that geneticists have thought of as well and attempted. Sampling cells from a few different reproductive cell lines should theoretically provide a strong average, perhaps with some adjustments for more common mutations across all lines/things that are more likely to be repaired. Then regenerate the telomeres and replace the DNA in the germ layers of a blastocyst and you have the foundation to replace 50+ years worth of cells, plus provide a digital copy of the DNA for the next treatment round. Keep supplying a person with "undamaged 25 year old version of their self" cells (based on telomere length) and they can stay young indefinitely without negative side effects such as continuing to grow taller, cancer from damaged DNA, etc. Still issues with arteries clogging over time, figuring out a good way to regenerate the brain, bones and joints wearing down, etc., but I feel like those are easier problems (with the exception of the brain), perhaps to which the young stem cell therapy could also be applied.
