Makes you dumber points at damage already happening to you. Everyone quietly suspects their focus is worse than it was. The plain red frame keeps it serious. The peak intelligence question adds a second worry, that your best thinking might be behind you.
How the packaging works
Title
The title states the damage bluntly and pins it on the viewer's daily habit.
Thumbnail
The question beside his face asks whether your intelligence has already peaked.
Remix this
If you teach focus, health or habits, name the harm the viewer already fears in plain words. Keep the frame bare. A stripped back image makes a scary claim feel serious rather than shouty.
The transferable lesson
Name the harm already underway, plainly and without decoration.
