As people grow older and become senior citizens, they tend to slow down their productivity and explore life as a retired person. Even during this stage of adulthood, however, they are still developing. It is during this time that they contemplate their accomplishments and evaluate the person that they have become. They are able to develop integrity if they see themselves as leading a successful life. Those that have developed integrity perceive that their lives have meaning. They tend to feel generally satisfied and accept themselves and others. As they near the end of their lives, they are more likely to be at peace about death. If they see their life as unproductive or feel that they did not accomplish their life goals, they become dissatisfied with life and develop despair. This can often lead to feelings of depression and hopelessness. They may also feel that life is unfair and be fearful of dying.
