Why is the alcohol age 21 and why is it taken too seriously?

yeah i agree the drinking age in the united states is kinda ridiculous but its also based off the fact that your brain isn't fully developed until your aorund 21. Binge drinking can cause stunted development of the frontal lobe of your brain.. which by the way controls your ability to make good common sense decisions. it should be 18 or 19 though. i think that's reasonable
