I think it does depend on the maturity of the individuals and what they want out of life.

I was married the first time at 24, then this time round at 34, whatever age you are, it takes hard work and more than just love to make it work.

My mother was married at 18, and my niece at 19 the same age as my sister, who has been married 32 years now, personally I would have hated to marry so young, not for me, I think an average good age would be around 26-28.

I think marrying in the thirties is a little harder, as you become so set in your way's, well from my experience, the first few years were fun but ever so challenging, and a period of real adjusting for us both, now we are settled, like the old comfortable shoe and sock lol.
