I was surfing the internet some days back,I came across this article “Get Married First, Then Focus on Your Career” it goes thus:
Women who want to have kids should make it a high priority in their early twenties to find a partner. A Newsweek cover story, Marriage by the Numbers, says is okay to wait until after 35 to get married. Newsweek is revising the saying that a woman has more chance of getting hit by a truck than getting married after age 35.
But the article ignores one of the most pressing issues facing Generation X: Infertility. No generation of women has had more trouble with fertility than this generation who received the terrible advice, “Wait. You have time. Focus on your career first.”
In fact, you have your whole life to get a career. This is not true about having a baby.........http://www.workgist.com/get-married-first-then-focus-on-your-career/

I'm sure most ladies would agree.

If the means, maturity in character and the opportunity are there, every woman is good to go at age 22 and man at age 25.
This is my opinion and view. But the reality in most cases does not this feasible plus individual differences and ideology.
When it comes to marriage, always remember that the earlier the better but first be a forward moving individual.
