This is technically an invalid argument because the drinking age is already at twenty-one years of age.
I think that the drinking age should be lowered from twenty-one to the age of twenty. If you want to be technical, it should be eighteen. Eighteen is the supposed age that an individual becomes an "adult." If one is an adult, they are old enough to make their own decisions. They should also be able to decide whether they are old enough to drink alcohol or not. Many people say to somebody "You are an adult now, you can make your own decisions." If this is true, why can't a person be able to drink alcohol when they are at the age where they are considered an adult (a.K.A. As I state again, the age 18)?
