Do you think it's better getting married at age 30 or age 40?
Unless you are a woman who is really keen to have children and raise a family, urgency is not the question here.
Every successful marriage comes down to the same important factor. Two compatible people meeting and having a lot about each other that they like.
And can see themselves in the same house/apartment, the same living-room, the same bathroom, the same bedroom together - and are happy with that.
Women who want children and a family shouldn't really be waiting till they are past 40, as there are all sorts of physical problems involved, and kids are also better off with younger fathers who can relate better to their physical activities (although - bear in mind that grandparents are often called upon to bring up their grandchildren and often do a better job than the parents did - so age isn't always a no-go).
The most important thing, I repeat, is to find the right person. And if that means waiting, so be it.
