Actually, the "aging" of the Half-humans is really weird and probably not accurately compared to normal aging in most organisms. While they seem to break down in some manner, their external appearance and physical abilities don't seem to diminish as normally does during the aging process. They don't get wrinkles, or suffer from the normal breakdown of tissues that we associate with aging.

Instead, it seems like their systems just kind of.....start breaking down in some manner. Arima develops Glaucoma, which is something normally associated with the elderly.....but otherwise, his body seemed fine. Even so, he states that he was close to dying.

Kanou also hints that artificial OEGs can suffer from a shortened lifespan, as a result of extreme cycles of regeneration.

But like I said, OP's assessment is.....sort of accurate? In that the average human lifespan is around 80 - 90 years, while it seems that Half-humans only live to be in their early 30s. So that is literally 1/3 of the lifespan their parent species' can potentially live. But it isn't accurately called "aging", since their bodies don't seem to undergo the same kind of aging process that we're used to thinking about.

Rather, it seems like they hit their late 20s and just kind of start breaking down all at once. They remain physically strong and externally youthful, but internal systems start breaking down from the strain.
