change the drinking age from the age of 21 to the age of 20.

It should be known that the drinking age is already preposterous as it is, Mr. Obama.
I was going to say eighteen should be the appropriate, but perhaps it's still a bit too young.
Twenty years of age is perfect, you're out of your teenage years, you're also at the point in your life where your going through major life changes.
Hear out my petition, a one year change wouldn't harm anyone.
If anything "underaged" minors are being charged for drinking, especially at the age of twenty, when their legal drinking age is so close to the point that they'll go to out of their way to purchase false identifications. This is bad.
Thank you very much for your time.
