We have simlilar issues her in the land of Igloos as it is a provincial (State) governed law and we have 3 that are 18 yrs and the others are 19 yrs.
liek everywhere we have issues of underage drinking, I for one participated gleefully in the 80′s, as did you all in some manner or not.
but being a nanny to an adult is pathetic and has done little to curb the issue in the US. you have higher instances of binge drinking, and fatalities due to binge drinking than we do per capita.
the idea of serving your Country, voting for its leaders and getting married but not being able to have a legally legislated substance seems a tad pathetic, since you actually can do nothing to stop them in the end, ends up being futile.
all the BS stats that are thrown around are nothing but lies in order for a puritanical organization to gain memberships and funding and a means to control a population.
if you wanted to really stop drinking and driving why not just legislate that in-car breathalyzers be installed on all vehicles. that stops the problem no….never happen! not in a hundred years!
