Thanks for the nice comments here and from Carol in the other thread!
It doesn't seem like it could have been 50 years.
On November 30, 1955, my great grandparents celebrated their golden wedding anniversary and way back then that was unheard of. Now, every week's local newspaper has at least one 50th anniversary being celebrated. And on our news radio station there are obituaries of couples married 74 or more years quite often. Now that is a long time.
