^I'm just going to throw out my interpretation.

This is how I want to see it. The human body with it's fixed amount of RC cells grows/matures 'til the age of 20-22. But Ghouls grows/matures constantly, because their amount of RC cells is much much higher and can be altered by eating. They're constantly evolving/growing.

The fact that the growth runs out in humans at a certain age, creates a conflicting reaction with the RC cells that want to keep evolving within the bodies of Half-Humans. And those symptoms are deficencies we see in Arima in most likely soon others. The RC cells keep them in top-shape, but the human genes/structure can't keep up with the growth and they just stop working all together.
