“Do you know how long a year takes when it's going away?" Dunbar repeated to Clevinger. "This long." He snapped his fingers. "A second ago you were stepping into college with your lungs full of fresh air. Today you're an old man."
"Old?" asked Clevinger with surprise. "What are you talking about?"
"Old."
"I'm not old."
"You're inches away from death every time you go on a mission. How much older can you be at your age? A half minute before that you were stepping into high school, and an unhooked brassiere was as close as you ever hoped to get to Paradise. Only a fifth of a second before that you were a small kid with a ten-week summer vacation that lasted a hundred thousand years and still ended too soon. Zip! They go rocketing by so fast. How the hell else are you ever going to slow down?" Dunbar was almost angry when he finished.
"Well, maybe it is true," Clevinger conceded unwillingly in a subdued tone. "Maybe a long life does have to be filled with many unpleasant conditions if it's to seem long. But in that event, who wants one?”

“I'm not buying this. If, if you're eleven years old, or twelve years old, thirteen, and you have a strong bond with your family, OK. Even if the guy [kidnapper] threatens you - this and that. … If you can get away, you get away.”

“How old do I think the earth is? You know what? I don't have any idea. I know it's pretty old, so it goes back a long, long way. I'm not sure anybody actually knows completely and absolutely how long, how old the earth is. I hear your mom was asking about evolution. You know, it's a theory that's out there. It's got some gaps in it, but in Texas we teach both creationism and evolution in our public schools, because I figured you're smart enough to figure out which one is right.”

“Why were you so old when we met? I answered with the truth: Age isn't how old you are but how old you feel.”

“Every man has to settle down eventually. You know why you gotta settle down eventually? Because you don't want to be the old guy in the club. You know what I'm talking about. Every club you go into, there's always some old guy. He ain't really old, just a little too old to be in the club.”

“I don't know how it is that you start working at something you don't like, and before you know it you're an old man.”

“Do you know how sometimes - when you are riding your bike and you start skidding across sand, or when you miss a step and start tumbling down the stairs - you have those long, long seconds to know that you are going to be hurt, and badly?”

“You know you're getting old when you stoop to tie your shoelaces and wonder what else you could do while you're down there.”

“That's what birthdays were. Days when you found out where you stood. Who was on your side and who wasn't. Nothing to do with how old you were.”

“People assume that I'm wiser than I am because I'm somewhat successful. Age does not bring you wisdom, age brings you wrinkles. If you're dumb when you're young, you're going to be dumb when you're old.”
