—Daniela Marx, Sarasota, Florida Welcome to the only club that is growing while it is shrinking! Assuming your doctor was unimpressed (no osteoporosis, etc.), then yes, you may be losing height due to normal aging: The disks in our spines become slightly flatter over time. Women gradually lose 2 or 3 inches after the age of 30; men lose 1 or 2 inches. But don’t forget your posture. Many of us begin to slouch as we get older, and if that goes uncorrected, we can’t stand up.
