>>52921673The prefrontal cortex doesn't stop developing until you're 25, it's the part of the brain responsible for decision making, foreseeing consequences, impulse control, emotional reactions, etc. Biologically you're still an immature child before that age (which is why late 20s dating a 18yr is grooming, their brains quite literally aren't ready yet and are easier to be molded). 18 is an arbitrary number, you magically don't become a responsible and mature adult the moment you the clock strikes midnight.
