A 20-year-old is typically a young adult who has recently transitioned from adolescence to adulthood. This age often marks significant milestones, such as completing high school and possibly starting college or entering the workforce. At this stage, individuals may begin to explore their independence, make personal decisions, and establish their identities. In many cultures, turning 20 signifies leaving teenage years behind and embracing responsibilities associated with adulthood. This age can also bring about changes in social dynamics, as friendships may evolve and new relationships form. Many 20-year-olds are focused on education, career development, and personal growth.
