Everything in moderation is a great motto to follow for your entire life. No matter what age you are, drinking stupid amounts of alcohol, is, well, stupid. It shows you have no respect for your body, your mind, your health. Without your health you have nothing, and I have a tough time respecting anyone who can't even respect themselves. 😎
As for underage drinking specifically, I don't think you should drink if you're really young, but around 18 it greys - after all, in Alberta the legal drinking age is 18, and here in Saskatchewan it's 19, so, well, close enough. 😱 😉
I did a lot of underage drinking and binge drinking, so I'm speaking from experience. And now that I look back on it, I was an idiot. I am glad I am wiser now and care more about my health and well-being. I understand you don't think about these things as much when you're younger, perhaps it's a "phase", and I appreciate that, but it still doesn't make it right or a good overall choice. And anyone who thinks it's cool is simply kidding themselves and quite frankly is immature. 😎
