Why to wait until be 21 to drink?

In the article "Drinking age" Ross states that the major issue is not allowing 18 to 20 year old teenagers to drink since the legal age to drink in the United States is 21. In my opinion, I agree with Ross’ comment mainly because I lived in South America when I was 18 and I was allowed to drink and therefore, I forced myself to be more conscious of my acts. I think that by allowing 18 to 20 year old teenagers to drink, teenagers will become more responsible. I even think that car accidents, smuggling, and any other issues associated with teenager’s misdemeanor because of alcohol consumption will reduce. Moreover, by allowing teenagers above 18 to drink, Texas Government has a chance to provide further education to our young people above the use of the alcohol and its consequences. Our major goal as citizens is to do our best to prevent and reduce any type of harm to our society even if it leads the Texas Government to change its current law.
