By the way, there is mounting evidence that kids are staying infantile longer and longer, and living at home as dependents at increasingly older ages. AS SUCH, there is a strong case to be made for INCREASING the age of maturity for: voting, military service, drinking, driving, marriage, gun ownership, contracts, etc. This recent phenomenon should be on the table as well.
Perhaps we should look into the cause of this, and rectify this issue, before we make even more drastic changes to society.
