Hell is an itch that can't be scratched. Dante understood this. In his Inferno, he describes a ditch in the Eighth Circle of Hell where alchemists, counterfeiters, and liars are subjected to the burn of an eternal itch.
The good news is that most earthly itches are in fact scratchable. Physical itchiness is usually a temporary sensation. But while most itching resolves on its own, 10 percent of people suffer from some form of chronic itch during their lives. Scratching may provide temporary relief, but it also promotes more intense itching, which makes you scratch harder.
