Personally I believe that the fundamental driver of aging is dna damage. The direct issue is cancer, but the indirect consequence is that the body slows down cellular reproduction to counteract said cancer. This means slower healing of any injuries, and lower vigor. Thus I see any aging treatment that doesn't fix dna damage as fundamentally a blind alley. And conversely if someone manages to fix dna damage, then the rest should just be some small details.
