I most certainly would have benefited from something like this when I was young. When I joined the military I knew nothing about drinking alcohol except you weren't supposed to stop. Although there were a few "incidents" as a result of my drinking--okay, a lot of "incidents"--nobody ended up injured or dead. Was I lucky or what? I'll leave out the details of all the stupidity. There isn't enough room here anyway.
As an example to our children, Kathy and I drink moderately and responsibly. We also talk to the kids about responsible drinking and so far it seems to be working. The idea of a provisional license to drink alcohol appeals to me as an opportunity to provide experience which would presumably help young people make better decisions later on.
