I see now.

And that's mostly the point I am against, in my post.

From what I have read about genetics and related subjects (which isn't much, I admit), I have a distinct impression that the fact of our systems going down steadily is only "designed" in that respect that it is not (broadly speaking) evolutionary critical that humans survive past the age of raising their children, therefore, there seems to be no natural selection of long-lived humans.

That would change, if more people raised kids later in life though. And, of course, we must take into account secondary advantages of having groups with long-living humans -- as long as their long lives benefit the group as whole.
