Create a complete YouTube Short package that debunks a common myth. The script should present the myth clearly at the beginning ('Myth: You only use 10% of your brain'), then quickly and decisively debunk it with a surprising fact ('Fact: You use virtually all of it, even when sleeping'). Use a split-screen or dynamic text visual. Provide a viral SEO title, a description explaining the science, and at least 10 relevant comma-separated tags.
