Adulthood: where does it begin? In reality, that answer kind of depends on which metric of adulthood you're looking at, as the minimum legal ages for things – ranging from driver's licenses to military service and legal recreational cannabis – varies. Across the gamut of minimum legal ages in the United States, one thing is consistent: there is no consistency.
Are there some things that the minimum age requirement is too high on, though? Is it fair to require people to be 21 to legally purchase alcohol? Is 18 a good minimum age to set for tattoos without parental consent?
