I suppose Canadien (and German, et al) brains develop faster than us Americans.
I somewhat agree with this but my observations from a long time ago lead me to believe that the fact that it is illegal leads to binge drinking. If one can have a drink anytime the novelty does wear off (for most) and their is less tendency to overindulge at every opportunity. Now I am sure I exercised better judgement at 21 than 18 but I also know I exercised much better judgement by the time I reached 30 and I really don't think I was slower to develop than my peers.
I have looked at some of the research that is"not open to reasonable dispute." and I think the age 21 is somewhat arbitrary.
Do you know any 21 year olds that go get plastered on their b-day because it is finally legal? Good judgement? At least they are not hiding it and are more likely to have some sober support.
Oh 21 is certainly arbitrary. 21 is just 3 years older than 18 and that much more matured. The brain isn't really pretty much done til 25 or so. There a good reason that car rental companies wont rent a car to anyone under 25 Its just as matter of risk statistics and private firms are not constrained by political considerations What I was referring to as not open to dispute was teenage brains aren't done.
