Not once, in my entire life, have I witnessed my parents, grandparents, or siblings drink alcohol. As a teen, I've seen my sister post a pic of a glass of wine and I've found alcohol in my other sister's room
(which she lived in with her underage boyfriend - fun times). I've never seen anyone
drink it (unless medicine counts). Wine is for cooking in my house. Something my grandfather has always said is something along the lines of "I never want to be in a position where I don't have control over my actions". With being raised on those words and knowing there IS a line of alcoholics in my family, I'm personally choosing not to drink because I'd rather not risk flipping the switch. Hangovers and the potential danger of it does NOT sound appealing, anyway.
In college, my mom was always the designated driver. She teamed up with her friend who worked at a film developing store and she'd basically blackmail the people she drove into gas money by taking pictures of them drunk/puking and threatening to send them to their parents. Best (or worse) part was that these people would keep coming back to her.
Drinking, as its always been, is the social norm and it's the cool thing to do underage. Peer pressure and popularity seem to be the root cause of most teen deaths. Even adults who don't drink are pressured and teased, just as casual sex is becoming the norm and young and old virgins are bullied. How on Earth does it hurt you? The foolishness and danger of drunkenness is what hurts. Why are people blind to that?
Personal stories/off-topicishness aside... (hoping this makes sense)
I think it's fine how it is. Why go through the trouble of changing it? I think arguing that kids/teens are going to drink anyway is a silly excuse. Teens are going to smoke/do drugs "anyway", but does that make it OK? No. WHY should we
really lower the age? It's obviously not going to make teens more mature or responsible, so all it would do is make alcohol more easily accessible to MORE immature and irresponsible people. I see no benefit in that. Sure, it's everyone choice whether to drink, but it makes more sense to make the legal age where people have to wait to make the choice until their brains are closer to full maturity (by age 25, I believe). What was said about transportation is also a huge factor, as well as it making it more difficult for the underage to obtain it. The law changed 30-some years ago and for good reason. Teens drinking despite the law is no reason to make alcohol more accessible to young people. I don't see the logic in that.
