yeah so the whole "dead by 30s or 40s" are a misconception. Read this for further information:

But TLDR: as long as people hit 25 back in medieval time, their life expectancy is 25.7. This means that people in that era who celebrated their 25th birthday could expect to live until they were 50.7, on average — 25.7 more years.
And MC is already in his 20s, so he definitely will live to 50s even if he wasn't an immortal vampire lord.
Though that does mean he can't just say he looks young until 50s like I expected.
Go back and remove that "dumb" rating, because that's NOT WHAT I SAID.
What I was talking about was at what age people are considered old DURING THAT TIME PERIOD.
MEANING: NOT BY THE RECKONING OF OUR MODERN STANDARDS.
And I never said that people never got to be older than 50. I only said that the ones who did make it that far? They were considered old as fuck
DURING THAT TIME.
Also, that article of yours is more of a blog post than a scholarly article. The author says that "a lot" of people lived to what we consider old age in our modern era. But what he leaves out is that it's only "a lot" if you're only looking at that one group without considering the rest that form up that average figure.
And the fact that the author uses the term "a lot" is why it's a blog post and not an actual scholarly article being published in one of the big science journals. "A lot" is a very, VERY subjective phrase, and not something you often see in such articles. The only time you do see the word "lot" used in peer-reviewed articles is when its referring to "batches" and "lots".
But ultimately? That link you posted is actually supporting my argument, because:
- It is entirely subjective - old age as we see it in the modern day versus old age as it was seen in that time period. And...
- That, even though there were people who did indeed live to their 70's and 80's, the vast majority of people were keeling over in their late-40's to early-50's.
It lines up
exactly with what I actually said: "IRL during this time period, you're an old timer by the time you hit forty. If you somehow make it into your fifties? You're not just over the hill, you're older than freakin' dirt."
Seriously, when you consider the human life cycle and scale it to about 50 years (the average lifespan of land owners as indicated by the author of that article) and having the aging occurring where appropriate, Yuuki and Iris are gonna stick out like sore thumbs by the time they're 30 - exceptions or not.
In fact, Iris's grandmother was thought to be some kind of aberration for keeping her youthful appearance for as long as she did. She stated that when she met her grandmother, that she she looked like she was 30 years old despite being 50 at the time. (BTW: this is pretty fucking exceptional even this day-and-age. I know because my mother is one such person - 65 years old and she's STILL getting hit on by much younger guys, and right in front of her husband, no less!)
Which means, yeah, it has precedence... But it won't be considered in a favorable light.
And yes, this is the case. Go back and re-read Chapter 13. There is a serious implication there that Iris isn't the most well regarded in the royal family because of the sheer amount of magical power she has. Granted, this is partly because Iris is the daughter of the lowest-ranked wife, and yet she is the most powerful magic user among the other princes and princesses... and that's causing a fair amount of friction in the royal family.
And this was all borne out in Yuuki's duel with the knight-guardian of one of Iris's older sisters.
That said, the other royal children are already looking at her and going "WITCH! WITCH!" (Metaphorically, that is.) How well do you think they're gonna take it when most of them are starting to feel their age creeping up on them, but meanwhile she's thirty-five but still looks like she's twenty?
Also: You're wrong about the current ages of Yuuki and Iris. At the end of Chapter 1, Yuuki says he was ten years old when he regained his past-life memories. And at the start of Chapter 2, he goes on to say that event occurred three years ago, making him 13. And in Chapter 13, Iris clearly states that she is 13 as well. And only one month passed, from the duel between Yuuki and Zeros, to the time Yuuki left for the magic academy.
And I'm pretty sure they haven't finished their first year there, yet.
