Changes in Bone Density: With the advancement of age, the bone density decreases. It means that the elderly people especially those over 40 years of age, are more prone to bone injury than young people. In fact, it is due to decrease in various minerals such as calcium and phosphorus, found in the bones. Bones become less dense and more porous. The decreasing process of these minerals begins in the early 40's. Less bone density can result in osteoporosis and reduction of weight bearing capacity which may lead to fracture. There can be reduction in height due to the thinning of vertebrae.
