Although the skeleton is supposed to renew itself every ten years, as we age, it perhaps takes longer to renew itself and is also less efficient. (Ebraheim, 2011) Bones are therefore less dense due to inefficient production of bone matter. If the bone has previously been damaged/broken, as it becomes less dense it will also be more vulnerable to another break and/or weakness. (KidsHealth, 1994) As the bone becomes older and weaker, the person's posture will change and their movements will become less controlled and slower. A person can lose balance and when a person loses control of their movements they are more likely to lose balance and fall. This could then cause a second break as the bone is already weak and damaged. (Physiotherapy room,
