Why is biological aging not reversable yet? After all we've done and know... we still age and die... "on schedule"?

I thought genetic science would find that combination needed to stop it altogether. AT 68, I'm seeing differences from being 58 and 48... I'm reviewing concert videos from 2014 when Dorothy was 79 and she was doing excellent... yet at 90, she crumpled up died. This, despite all the supplements I fed her in daily "supershakes".

I think it's time to review potential fraud in anti-aging along with the DOGE investigations. I would have thought by now we'd be seeing healty biologically 50 year old 130 calendar year old people as common. That's what the vision of the early anti-agers was.
