When your average baby boomer wakes up and discovers he's old, it might not be the funniest moment of his life. But Dave Barry isn't your average boomer. And he doesn't read this--his hilarious account of turning 50--with the expected whining grief of someone whose world has become utterly pointless. No, where others might shriek in horror at the thought of getting "wrinkled, and forgetful and achy, and that you gain weight merely by watching food commercials," Mr. Barry takes a much more mature and less-panicked approach--he cracks jokes. For anyone accustomed to Barry's writing, with its trademark drollery and knowing wit, his off-handed narration and casual, Everyman's voice will bring an added pleasure to his hysterical observations on the golden years--especially if their eyes have started to go, along with their teeth and hair and other remnants of fleeting youth.
