Arnie could go at anytime?
This is my second post on this film.
My question is, what was it supposed to mean when Gilbert said "Arnie could go at any time"? I assume he means dying...but how? I understand that Arnie had a mental defect. But how did that give him a greater chance of dying? His brain was the problem, not his overall health. Or am I wrong? Can someone help clarify this for me?
