Sadly we are all going to get shorter! We lose height because the discs between the vertebrae in the spine dry up and compress. The aging spine can also become more curved, and vertebrae can due to loss of bone density. We also lose muscle in the torso which can contribute to a stooped posture. Even the arches of your feet can drop and make you slightly shorter.
Estimates vary, but on average people lose ¼ to ½ inch every decade after age 40 or 50, with losses increasing in later years, and women generally losing more than men. Research from the Baltimore Longi¬tudinal Study of Aging, for example, found that women lose an average of 2 inches between the ages of 30 and 70 (and just over 3 inches by age 80). Men lose a little more than 1 inch by age 70 (and 2 inches by 80). But averages hide wide variability: Some people lose an inch or more in a single decade, some shrink only when they get past 60 or 70, and a few don’t shrink at all. Sadly I am not among those!
