>Because ageing and dying is more optimal for the survival of the species than immortality (or technically, not ageing).
More accurately, immortality was never necessary for reproduction, so our DNA never got rid of this protein and others that are responsible for aging.
To really understand what's going on, we would have to know how common it is in other animals and what else, if anything, it's responsible for.
Some creatures do not age, so at this point we don't know whether aging is something "left over" that incidentally affects our branch on the tree, or whether it's necessary.
That's the pure-evolutionary view, anyway, which I don't put much faith in.

It sounds like they are just confirming the meme that Asian women start rapidly turning into meemaw by 50.
This is all stock settings women, anyway.
Glycine, collegen, child blood, hyaluronic acid, and other things can make a big difference.
