An eighteen-year-old is a person who has reached the age of 18, marking the transition from adolescence to adulthood in many cultures. This age is often associated with new responsibilities and rights, such as the ability to vote, sign contracts, and make independent decisions. In many countries, turning 18 is celebrated as a significant milestone, often referred to as a "coming of age." In many places, the age of 18 is also when individuals can legally consume alcohol, join the military, and apply for a driver's license without parental consent. This age is crucial for personal development, as many young adults begin to pursue higher education or enter the workforce, shaping their future paths.
