Answer:
2 inches
Step-by-step explanation:
People generally decrease in height as they age from about 40-50 years of age. On average however, women lose more height than men as they age. Studies have shown that women lose 2 inches in height between the ages of 30 and 70 and above 2 inches from 80 while men lose just above 1 inch from 70.
Loss in height is generally because of loss of bone density at old age, the discs in the vertebrae begin to compress and the spine curves.
