The term "-18 (Age)" refers to individuals who are under the age of 18 years. This age is significant in many countries as it marks the legal threshold for adulthood. People under this age are often considered minors and may have restrictions on activities such as voting, drinking alcohol, and signing contracts. In many societies, being under 18 also means that individuals are still in school, typically attending primary or secondary education. Laws regarding the rights and responsibilities of minors vary by country, affecting areas like employment, criminal responsibility, and parental consent.
