In addition to the various minimum age requirement for firearm possession/purchase, military conscription/enlistment, etc. discussed above, consider the following:
Age of candidacy
Age of consent
Age of criminal responsibility
Legal drinking age
Legal smoking age
Legal age for cannabis use
Marriageable age
Voting age
(among others)
It's lawmakers who decide to legislate all the "age" distinctions and requisites. Who better to objectively evaluate evidence and create a sound public policy not based on any kind of bias or subjectivity (or political pandering)? You know, like with "multiburst trigger activators". True, they may rely to some degree on "experts" who pull numbers out of their ass based upon advocacy "research" and heavily leftist academia with its rewards for "discovering" the "truth" known to the lefties all along. The fact that they change their mind every decade or two and move the requisite ages up and down all over world is of no concern. Trust them. They know what they are doing.
Side note:
The age of consent in Hawaii is 16. There is however a close-in-age exemption, which allows those aged 14 and 15 to consent to sex with those less than five years older.
Previously
the age of consent was 14, the lowest in the United States. Avery Chumbley, a member of the Hawaiian Senate, had made efforts to raise the age of consent. The age of consent was changed to 16 by Act 1, House Bill 236, passed by the Legislature of Hawaii in 2001.
That means that if someone was legally having consensual sex with a 14-year-old at the very moment the new law went into effect that person immediately became a felon for doing the same thing they were doing legally the literal moment before (assuming that person was more than five years older than the 14 year old). How did the 14-year-old actually, in reality, change at that moment to warrant felonious activity? Now, be sure to turn in or destroy all those "devices" that "simulate automatic gunfire".
