Is marriage before age 25 a recipe for disaster?
Marriage, at any age, can be a recipe for disaster. It is false assumption that younger people are unable to commit to relationships and marriages, or that they all lack the maturity to make a marriage work. That simply is not the case. I know plenty of middle-aged people who have not been able to make their marriages work, either. As jkisses said, the success of love and marriage is dependent upon the various factors involved in the relationship between two people. There is no broad statement or generalized ideal that applies to any demographic because you can not successfully apply generalizations to a thing that is unique.
