Underaged drinking is illegal, and there is a reason we have a law for it. Part of the reason is because of the National Minimum Drinking Age Act of 1984. We have to either wait until 21 years of age, or lose up to 10 percent of federal highway funding. Couples of other reasons is because, before the age of 21, your brain is still developing. Another reason is because drinking at a young age can hinder certain things inside. Plus it puts your health at risk. And especially in today's generation, we are messed up. I should know. I was born in 2006. Kids today are all about themselves. It's me, me, me. We already make messed up decisions. So underaged drinking isn't that good of an idea for us.
