The concept of personal continuity, or personal identity, refers to an individual posing questions about themselves that challenge their original perception, like "Who am I?" The process defines individuals to others and themselves. Various factors make up a person's actual identity, including a sense of continuity, a sense of uniqueness from others, and a sense of affiliation based on their membership in various groups like family, ethnicity, and occupation. These group identities demonstrate the human need for affiliation or for people to define themselves in the eyes of others and themselves.
