Question: It's stated a couple times in the movie that Arnie could die at any moment. Pardon my ignorance, but why exactly is this? Is there something about his condition that makes him highly susceptible to dropping dead, or is it a matter of his behavioral impulses (such as climbing the water tower) that put him at a high risk of dying in an accident?
Question: When Gilbert and Arnie first meet Becky they tell her that Arnie's birthday is in 6 days. It is indicated that Mr. Carver dies and is buried sometime in between then, but if he died say two or three days before the party normally it would take about a week to plan a funeral. Are funerals planned quickly in smaller towns in the real world or is it just for the film?
