With research pointing to brain development being incomplete until the mid-twenties, it seems we should be _raising_ all age limits: age of majority, drinking, voting, military service, etc. People "consenting" to die for their country or get married before their brains are fully developed just sounds wrong to me. And voting? Why should someone with an idealistic view of the world due to youth and inexperience be given a voice in running the country? If we're not going to raise voting age, then make people earn their franchise.
