Y ou maybe correct about following natural remedies. But you are wrong about several things including “just listening to his YouTube” There are 3 parts of gray matter -The Cerebrum, Cerebellum and the Brainstem. And the parts of White matter of brain- the corpus callosum. The corpus callosum integrates information across cerebral hemispheres and thus serves an excitatory function in interhemispheric communication and giving information to gray matter for you to make voluntary changes. While you’re just ‘listening’ to YouTube, you don’t know the information getting in your head is making you voluntarily act in a certain way that maybe bad for your health.
