In my opinion, there is no magic number for a marrying age - it depends on the person.

I was married in the early 60's - right out of high school - but that was quite common back then. I was 18 and my now ex, was 23. We were together for about 35 years before we separated, and it was only 3 years ago that we decided to divorce. Would I do it the same way again?? - no. There are things that I would want to do on my own before marriage, and not with a husband, after marriage. Was my life miserable because of this?? Nope - not by a long shot. I had my kids when I was young, and grew up with them, and had fun and was able to keep up with and relate to the younger set. I for one, can't imagine myself starting a family at 40+ like so many women do today. I wouldn't have the patience or the energy.
