Your country’s definition of “of age” and my country’s definition of it is likely to differ. Easier to just implement a birthdate field than try to cover all the global legislations for these things. Especially when there are multiple conditions for “of age” in a single country. Old enough to vote? Old enough to drink? Those are often not the same.
Most of the laws aim for social media, so the 2 bit solution should be enough for most legislation. I would propose an “Birthday” field for legislations where an exact date is needed (which shouldn’t be, because it’s allowing every tracker to identify the DoB) and the “2 bits” for the rest. In my country the ages are 16 for drinking beer/voting and 18 for “mature”/hard liquors/tobacco.
