I was never the diplomatic diplomat.

Older fatherhood isn't all bad: testosterone rates drop about 1% per year as men age, making them less reactive and more patient, and a professionally established middle-aged man is likely to have more time and money to devote to his kids than a twenty-something who's just getting started.

My grandparents got married at a very young age, and a lot of what I think about marriage is based on their relationship.

No Congress ever has seen fit to amend the Constitution to address any issue related to marriage. No Constitutional Amendment was needed to ban polygamy or bigamy, nor was a Constitutional Amendment needed to set a uniform age of majority to ban child marriages.
