" But the kid could think, too. He wasn’t academic like Joe, but he was practical. His IQ was probably about the same, but it was a get-the-job-done type of street smart IQ, not any kind of for-the-sake-of-it cerebral indulgence. Reacher liked facts, for sure, and information too, but not theory. He was a real-world character. Stan had no idea what the future held for the guy. No idea at all, except he was going to be too big to fit inside a tank or an airplane cockpit. So it was going to have to be something else. "

― Lee Child , Second Son (Jack Reacher, #15.5)
