Typically, in most of the countries, 18 is the age from where the independent life of a person starts, and one can take decision by itself. However, few other countries still restrict them to do several things until the age of 21. In my perspective, 18 is the best time to be considered as an adult, yet few limitations need to be imposed until they get mature enough; for instance, getting married or drinking alcohol. I will further discuss the reasons for this.
