I have no commitment either way, but as a longevity strategy ultimately what will kill you is running out of useful mitochondria or stem cells.
So do you do your best to reduce turnover, rescue what you can and maintain a healthy population for as long as possible to increase possible lifespan. The alternative is keeping everything at optimal level in order to have the highest level of health to prevent disease, which will reduce potential life span, but give you the best quality of life in senior years.
I’m leaning more towards healthspan over lifespan these days, but that may change as with new theories, mechanisms and studies emerge.
I’m not convinced that just because there are epigenetic changes in old cells they are always bad. Lifestyle changes can have both good and bad impacts, and if you have spent a good period of time on a protocol such as low protein and CR, rescuing old cells with epigenetic changes may be worthwhile.
The question is how much of a tangible difference there is to these two approaches on how long you live; my guess is not a lot.
