25 - 30
For a former next door neighbor... 91
Its up to the individual. I'd like to aim for late 20s/early 30s I think I'd have my act together by then and out grow bad habits.
Just before death to prevent death tax
That is highest individual. Generally speaking from my experience. A good age to began to settle down in a mature manner is between the ages of 30 & 35. I've only written that because in the USA both black & white culture's don't do a good job of teaching thier youth to find themselves earlier on. By this time maybe there has been enough emotional bruises & lessons for that person to know what he or she want's in a marriage. Of course that does'nt always work. Bottom line in today's America, wait until your older, but then again that is highly individual.
35 to 40 and he should marry someone younger, lol
