From birth to old age, the body undergoes many changes. As we get older, these changes alter the ways that the body can compensate for the stress of illness or injury. It is important to understand the physiology of normal aging in order to anticipate an older person's response to changing conditions. Activities that were done easily as a younger person may become more difficult or impossible, requiring additional help or changes in the task.
