The govmnt has issued aluminum foil lined helmets to the guys with the keys.
For a time there was a rumor that wearing an aluminum foil cap on your head increased the possibility to talk with aliens. That was a myth perpetuated by the govmnt,
as they want to limit our interactions with aliens. In fact the reverse is true, the aluminum foil cap prevents the human-allien mind meld. That is why I, like a lot of other folks won’t wear an aluminum foil cap on my head.
