"The children in school grew up so fast. They, like their parents,
went about their professional career. In a flash they became gray and
grizzled, and were getting tired of life."

Is there a better expression than "gray and grizzled"? I want to express the subject's appearance getting older, their skin with more and more wrinkles, their face with increasing spots, and hair turning gray. Is there an expression or word that would vividly depict this feeling of "getting older in appearance"?
