My Father and Grandfather were traveling in an auto in 1940 with a gentleman in the back seat during a 7 hour trip. The man in the back seat was talking to them.
After about 5 hours he didn't answer. They looked back and thought that he had falled asleep. WRONG!
They drove him home! Then the circus began!!
I'd like to pass away quietly in my sleep like Uncle Bill, not screaming in terror like the passengers in his car.
