Legal Drinking Age

I think that it should be changed from 21 to 18. Kids younger than 18 are still getting alcohol. I think that if the age was lowered that many kids could be convinced to wait until their 18 before they try it. If you can be convicted and sentenced to life at the age of 18 then why not lower the drinking age. Many kids do know how to drink responsibly and it's the ones that don't that cause trouble. But they would probably get into more trouble because they will still be getting alcohol any way they can and then it would be illegal!
