Hopefully this helps you get started:
The minimum drinking age is 21, and I believe that it should stay that way. This helps prevent motor vehicle crashes, it is reported that states that increased the legal drinking age to 21 saw a 16% median decline in these types of accidents. In the U.S. each year drinking too much has contributed to more than 4,300 deaths from people who were below the age of 21. In 2010, there were about 189,000 emergency department visits by people under age 21 for injuries and other conditions that were linked to alcohol. All of these facts show that underage drinking causes a problem, so the legal drinking age should stay the same.

All of the above can help to develop a character. A reader will have a clearer image of the character if they are given a description of what the character looks like. We also know who they are as individuals if we know their thoughts or hear them speak. Other characters' opinions of this character can also help to develop them, because we learn who the character is through other peoples' eyes. Hope this helps.
