Aging Changes in Body Shape
Effect of changes
Even healthy elderly people begin to appear bony, thin, and wasted, with a round belly and fragile arms and legs. Changes in fat and lean body mass may cause an aged person to develop a heavier-appearing body and thin arms and legs.
The distance between the fingertips when the arms are held out to the sides (arm span) is the same as the young adult height. As you age, your arm span may be used as a measure of your "true" height, or it may be measured in comparison to your current height to determine height decrease.
