The age of majority is termed the threshold of transition from adolescent to adulthood, which is conceptualised in law. This is a momentous landmark for most of us, when the chronological age ceased to recognized a person as minor, when they assume control over their actions, thereby terminating the legal control and responsibility of their parents.
For most countries, the age of majority is set at eighteen, and not necessary correspond to actual mental or physical maturity of an individual. In many societies, the age of eighteen also considered appropriate for the marriageable age, alcohol-drinking age, school leaving age, smoking age, voting age and the age of sexual consent. Although a person may attain the age of majority, there may still be a great variability in opinion in what is permissible and what is not.
