Illness is defined in a variety of ways, which depend on a number of factors. One of these factors is age differences. Older people tend to accept as “normal” a range of pains and physical limitations which younger people would define as symptoms of some illness or disabilities. As we age, we gradually redefine health and accept greater levels of physical discomfort. In Blaxter’s (1990) national survey of health definitions, she found that young people tend to define health in terms of physical fitness, but gradually, as people age, health comes to be defined more in terms of being able to cope with everyday tasks. She found examples of older people with really serious arthritis, who nevertheless defined themselves as healthy, as they were still able to carry out a limited range of routine activities.
