AI Overview
You are legally an adult at the age of majority, which is 18 in most countries and U.S. states, but can vary, with some places being 19 or 21. Adulthood is a legal status conferring rights and responsibilities, but reaching it doesn't always align with cultural expectations, brain maturation (which can continue until age 25), or personal feelings of being an adult.
Legal Adulthood
Age of Majority: The legal age at which a person is recognized as an adult and assumes legal rights and responsibilities.
Varies by Location: The age of majority is set by law and differs between countries and within the U.S. from state to state.
Common Ages: In the U.S., the age of majority is 18 in most states, but it is 19 in Alabama and Nebraska and 21 in Mississippi.
Rights and Responsibilities: Reaching the age of majority allows individuals to vote, enter contracts, work full-time, serve on a jury, and make their own medical decisions.
Other Perspectives on Adulthood
Brain Maturation: While legally an adult at 18, the brain continues to mature into the mid-20s, with some studies indicating brain development can continue until around age 25.
Personal and Cultural Milestones: Adulthood can also be defined by other significant milestones, such as financial independence, the ability to pay one's own bills, forming a family, or being married.
Coming-of-Age Ceremonies: Historically and cross-culturally, adulthood has been marked by rituals and ceremonies, but these vary widely in age and significance.
