Drinking Age 18? or 21?

One topic of interest that seems to go back and forth between the government a lot is the drinking age. Before The National Minimum Drinking Age Act of 1984 the drinking age was only 18. After this Act was passed the drinking age was obviously changed to 21, which is what it still stands at today. There are many arguments that I personally agree with about changing the drinking age back to 18. One main point being that at the age of 18 any person is considered an “adult,” treated like an “adult,” punished like and “adult,” so why is it that they can’t go out and drink at a bar like every other adult? Another point is if an 18-year told is allowed to serve for our country in war and also vote for the government positions, why can’t they drink alcohol? No one really thinks that deeply into the topic because it’s only 3 years and people who are already 21 probably say that it’s not that long, but for an 18 year old those 3 years seem like a whole lifetime. The last point that I’m going to argue is when you are 18 you usually still live at home for the most part. Although you only live at home for a couple of months, its still better than nothing, anyway, learning to drink at home in the comfort of your own home with you parents seems much more safe than starting to drink in college when you haven’t really done it even though we all know underage drinking takes place everywhere. Point being there should be people looking into fighting to change the drinking age back to 18 in order for everyone to not only be happy but safer also.
