The term "minimum age" refers to the lowest age at which a person is legally allowed to engage in certain activities or responsibilities. This can include voting, drinking alcohol, driving a vehicle, or entering into contracts. Laws regarding minimum age vary by country and can be influenced by cultural, social, and legal factors. For example, in many countries, the minimum age for voting is typically 18 years, while the minimum age for drinking alcohol may be 21 years. These age limits are established to ensure that individuals have reached a level of maturity and responsibility before participating in these activities.
