Answer:
Height begins to decrease on average after age:
50
Step-by-step explanation:
After reaching adulthood, which is typically around the age of 18-20, our height remains relatively stable. However, as we age, certain changes occur in our bodies that can lead to a gradual decrease in height.
One of the main factors contributing to this height loss is the natural aging process. As we age, the discs in our spine become compressed and lose some of their fluid, causing them to become thinner. This leads to a slight reduction in the height of the vertebral column, resulting in a decrease in overall height.
Additionally, the bones in our body may lose density and become weaker with age, a condition known as osteoporosis. This can further decrease height as the spine collapses or develops minor fractures.
While height loss is a normal part of the aging process, it is important to note that the degree of height loss varies from person to person. Genetics, lifestyle, and overall health can influence the extent of height loss experienced.
In summary, on average, height begins to decrease after age 50 due to factors such as spinal disc compression and bone density loss.
