I am writing a modern day story where the victim is buried alive inside a pine box, six feet under ground. If the victim actually remains calm, considering the circumstances, how long would they have before suffocation set in? Would hypothermia be a factor as well?
I searched google with the keywords: buried alive and premature burial, but only received info on the books, poems or movies with those titles/topics.
Edit: I'm not so much worried about the box collapsing or the dirt, etc. I need to know how long can a person usually survive before rescue comes.
