Slim sighed. “Kid, you’re going to die someday and so am I. And so is your pup. It’s the one thing we can’t avoid. Why, the ship’s reactor could blow up and none of us would know what hit us till they started fitting us with haloes. So why fret about whether your dog comes out of sleep-freeze? Either he does and you’ve worried unnecessarily… or he doesn’t and there’s nothing you can do about it.”
“So you don’t think he will?”
“I didn’t say that. I said it was foolish to worry.”
– Robert Heinlein “A tenderfoot in Space”
