The document discusses the differences between being 18 and 21 years old in terms of legal rights and responsibilities. At 18, one can work, rent an apartment, buy property, get a driver's license, sign contracts, open bank accounts, and apply for credit cards without parental permission. However, drinking alcohol is still illegal until age 21. The document argues that this is ironic given that 18 year olds can smoke, have sex, get married, fight and die for their country, so they should also be able to drink legally.
