Ya know, hinge, I read a really suggestive science fiction story years ago. Seems that cosmic rays or some crap like that was causing insanity, so they went for a more sophisticated type of tinfoil hat. Not being satisfied with the results, they armored vehicles and buildings with the same kind of shielding, and denser than other. Finally, they traced the early insanity to about the time we developed metal encased cars, planes, buses, etc. Guess what! Those cosmic rays or some crap like that were preventing all the insanity. Naturally, the improved shielding was counterproductive.
Time to reevaluate the tinfoil?
