The Proposal to Lower-the-Drinking-Age

The WaPo has a letter to the editor written by Molly Chabalowski that makes good sense. I think she is absolutely right to make this statement:

Drinking alcohol is legal for adults in this country. At 18, our young people risk their lives in military service, vote for president and can be prosecuted as adults. Yet we do not trust them to buy a beer and drink it responsibly.

I don't think the we should lower the drinking age to 18 since most young adults are still in their last year of high school when they reach the age of 18 (and have been know to shown up drunk at school).

Instead, I think 18 is far to young to allow anyone to sign up for military service or be drafted so why not move that age for military service to 21? Of course, that still leaves the problem that 18 year-olds can be prosecuted as an adults, so maybe we should change the law for adult prosecution to age 21 too. I think we either have to let 18 year-olds drink or change the age of military service and the legal status for adulthood to the age of 21.
