Occasionally I remember a story that I read one time while in fourth grade or so about a man who got trapped in a refrigerator railroad car and documented his process of freezing to death in the car. The irony is that the car wasn't refrigerated at the time; he died of thinking that he was going to freeze to death. Tonight I did some Internet searching to find out whether this is a true story. So far, I have only come up with the following two accounts:
Neither of these accounts quotes a source, although they are similar in their details. Maybe it's time to write to The Straight Dope on this one.
