And while we are speaking about tradition I want to present something I have noted before on this site that should make sentient people think. For over 100,000 years do you know what the average 15-16 year old female was called? Mom.
For over 100,000 years do you know what the average 35 year old human was called? Deceased.
So the 'traditional' marriage arrangement, or whatever it was called a long time ago, by necessity to enable human DNA to be passed on in a manner that would better ensure another generation, was a man (likely much older) to a girl. That was called normal. No one gave it a whit's thought. The past few generations where prosperity (primarily the abundance of calories on a fairly continuous basis) has enabled humans to change 'tradition' is but a very small sliver when compared to human history. So Big Mac, you have neither history, tradition nor current cultural changes on your side. You seem to want things in life to be fixed at the point (which is a very very small segment of human history) where you are most comfortable with them.
