Four women lunched on sushi. The conversation flowed and arced as it will among friends of long standing. One woman, however, was silent. She wanted to add her two cents' worth to this thread and that. But her brain had changed, had become a smooth, round ball of a brain. Once it had bristled with hooks valleys and thorn-like projections that snagged her thoughts and her memories, allowing her access to authors, titles, ideas, notions, and anecdotes as they passed by her brain.
Now, something was wrong. There were no thorns, no hooks. The outside of her brain was slippery-smooth, dimpled here and there with the holes left where hooks had been. You can't snag a thought with a dimple. So she remained silent.
Do brain-hooks re-grow? If she were to apply an expensive snake-oil directly to the surface of her brain would she be able to snag her thoughts as they floated by? Do you know how to spell "fat chance"?
