Good blog posting here. The best argument for lowering the drinking age is safety. The safest place to drink is a pub within walking distance of home or college dorm. Since this is illegal now, the under aged drink where ever they think they can get away with it. Often at a great distance, requiring a drive home after drinking. The bad part about youth drinking, is the drive home after imbibing. Lot of deaths, and permanent injuries, to say nothing of the number of smashed up automobiles.
Our children would live longer and get into less trouble if they could drink in on campus or local pubs.
I don't believe the current drinking age prevents teenagers from drinking. I am a parent and have some experience in this matter. I know that preventing them from drinking on campus increases the risk of death.
