Why Do We Shrink With Age?
As you get older, your body slows down. Each year after the age of 30, you lose approximately one heartbeat per minute off your maximum attainable heartbeat. This decreases blood flow and circulation. The chemical composition of your body changes as well. In between your bones, there is a cushion that keeps your bones from rubbing together. Over time this cushion retains less water and deteriorates.
As your bones settle in together, you lose a few millimeters at a time. It is normal to shrink by about one inch as you age. If you shrink more than an inch, a more serious health condition may be to blame.
