"So how long have I got, Doctor?"
The doctor removed his glasses and rubbed the bridge of his nose. "That's difficult to say. It could happen today. It might be six months down the line. There's very little we know about your disorder, except that it's always spontaneous, and it's always fatal."
"Jesus. I bet it's painful as hell."
"I don't know. I do know, however, that it's very sudden. You won't suffer long. It's over in a flash, if you'll pardon the pun."
"Wow. Is there anything I can do? I mean, to buy me a little more time?"
"Well there are some precautions you can take. If you have shag carpeting I would strongly discourage you from shuffling across it and touching metal. Avoid pullover sweaters. Keep away from open flame. Don't crunch Wint-O-Green Lifesavers. Common sense, really."
