Is chronological age more important?

For legal and developmental milestones, yes. But for understanding how someone thinks and behaves, mental age offers richer insight. Both matter in different contexts.

Can mental age increase over time?

Yes. Mental age reflects cognitive patterns shaped by experience. Growing responsibility, complex problem-solving, and reflection can shift your mental age upward.
