Age restrictions refer to laws or guidelines that limit a person's ability to engage in certain activities based on their age. These restrictions can vary widely depending on the activity and location, but they are often put in place for safety reasons or to protect minors from harmful behaviors or situations. Age restrictions may apply to things like driving, drinking alcohol, entering a venue, purchasing goods or services, participating in sports or activities that involve physical risk, or even voting in an election. The age at which someone is considered old enough to engage in these activities without restriction can vary from country to country and may be influenced by cultural norms, societal values, and historical context.
