Peaches and Dulcinea: who died (and)?

I don't know the exact phrase, but anyone pontificating
about anything and the way it should be,
might get someone else to say
"who died and made YOU the authority?"

And so it was, many years ago, that a writer wrote stuff, and over time, became the absolute authority on Angels, or the organizational management structure of Christian heaven.

Pseudo-Dionysius the Areopagite (that's his name, don't wear it out)
Has angels and sub angels and minion-angels.

Google wants to give credit to older texts, and they're right, Pseudo didn't just fall asleep one day and dream all this stuff up.

But it's cute.
Prolly wrong, but cute.

BEEEcause (eg and ibid)

Ahhhh, see?

I learned a new word today, (only I forgot it again)
"Hasbára" (I think)
It has to do with explaining stuff, but then it gets all specific and the generic meaning is lost.
Diplomacy?
Propaganda?
I guess it depends on who is saying it.
Here are two A1C diabetes charts.
One is very rigid, disapproving of my sugar.
Another is happy with it.

7.0 is good.

7.0 is NOT good.

I could pick and choose my hasbara's, I guess.
Plus the meter or the program ignores when my sugar goes low, saying it never happened.
I don't know what to make of that...

Rereading the first chart, um, well it starts out saying "Normal" so it might be targeted at people who don't think they have diabetes at all.
(insert wilford Brimley here)

It's a meme?

The second chart might be doable if you micromanaged doses like you were carefully doing a chemistry experiment, (think "Titration") but you might not get much done.

There's a 3-hour stacking rule I just learned 10 seconds ago...you live with your dose, whatever it was, for a minimum of three hours, before you start messing around with an added-on dose.
My body seems to maximize that rule; it's like some very slow-moving river.
But....
A guy wonders if the big-chunk dose a person gets every six hours, could be broken down into smaller doses?
Google thinks so, with all the standard disclaimers.
I'm not doubting it, I'm just doubtful of the workability...

Anyway,

Being topical

Variations on this riddle are spread out on the internet, mostly as chat-filler.

It only makes sense if one of them dies and stops aging, but that is not the answer they want.
They want a nice, neat, variable-ridden algebraic solution.

I cannot even come close to an answer, it's like there's a large sign in my head,
"TRICK QUESTION" (think, "Twilight Zone")
