You can't find your glasses (they're on your head), you forgot the morning staff meeting (it was an hour ago), and the kids are safely at school (but their lunches are still on the kitchen counter). Oh well, when you're crazy-busy, exhausted, or valiantly multitasking from morning till night, something's gotta give -- and it's usually your memory. Not to worry: A little memory loss is perfectly normal once you hit middle age, says Martha Weinman Lear, author of the forthcoming book "Where Did I Leave My Glasses? The What, When, and Why of Normal Memory Loss." But, guess what? You don't have to put up with it. Our 10 memory-boosting tricks will have you remembering where you parked the car in no time.
