Ok I'll tell you why it's 21
Age was 21 until FDR be like. Lower it to 18!! Then until 1980, drunk driving fatalies were high and group of whining cold hearted old women against drunk driving started to lobby and push congress around. Age went back to 21 and research said since that law happened death went down by 60%. (Fucking teenagers in 80's. fuck them)
However. Underage can drink under parent/guardian observation
There you go. That's the most important history fact for every Americans out there.
Fuck military, fack industry, feck Music, Fook gender history. It's all about food and drink history. The most important history of all. Thank you
