It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
We grow up and we don't look quite the same. But all this is only on the outside. Beneath the surface, your body is aging too, and sleep loss can speed up the process.
