It was 18 to drink in NJ when I was in High School. It was 18 for beer and wine in Delaware.
I have always wondered how legally 21 could hold up? You are a legal adult at 18. You can sign contracts and do time in an adult prison. Men over 18 must sign up for Selective Service and can be drafted if ever needed.(Yes ladies the military draft is still men only, the equal rights amendment has never been passed by enough States)
This video makes some great points. Let me know your thoughts!
