Oh, I definitely think region plays into it to. At home in NJ most of my HS classmates were just starting to get engaged/married in their late 20s, and I too got engaged at 28. When we moved to FL and got married two years later (at 30), many of my coworkers, because of my advanced age, asked if it was my first marriage! Everyone down here seems to be married by 20 and on their third child by 25. Now that I'm 32, I figure it's a matter of months before I start getting asked if I have grandchildren.
