From birth to death, every person goes through many individual situations that shape their development and behavior. Biography thus represents a subjective and individual life description that is unique to each person. Getting to know a person's biography often allows for a better understanding of their expressions and actions, needs, and feelings. This creates opportunities for positive influence and the promotion of well-being. In the field of elderly care, biographical work is gaining increasing importance. While in the past there was a deficit-oriented view of older people, focusing on what they can no longer do, there is now a growing emphasis on activating and resource-oriented care. The focus is increasingly on what older individuals can do.
