There is also a widespread rumor, which is almost totally untrue, that in the 1500s the methods of determining time of death were so archaic that coffins were designed so that, when buried, an apparatus (connected to the coffin at one end and a bell at the other) would protrude from the burial site. If someone where accidentally buried alive, or found themselves revived somehow, any movement in the coffin would cause the bell to ring and people would go dig 'em up. I say this is “almost” totally untrue because coffins fitted with those types of alarms, among others, were designed in the 1800s, though they rarely found practical application.
Point is, many people find anxiety in the idea of being buried for one reason or another. Of course, medical technology has advanced since, so we are generally more certain of time & cause of death.
Also, consider natural disasters like massive floods that wash up cemeteries and spread rotting, diseased bodies among those trying to survive. This happened during Katrina and people were getting sick from just having contact with the same water that the corpses were floating around in.
Plus, if One Eyed Willy had been buried, the Goonies would have been forced from their homes for God sakes…
Care to link us to any said “datas” that brought you to this conclusion?
Don’t forget that people have long utilized tombs throughout history. I suppose that could be considered burial as they were generally beneath ground and locked away, though they were often open structures so that kind of defeats the whole decomposition into the Earth theory.
