Age is not as important as readiness. Since women mature sooner than men their ages, the man should probably be five years older than the wife. Therefore, a woman, if ready and in love with Mr. Wright, who is also ready and in love with her, should be at least 25 and the man, 30.
There is no certain age for marriage, but if a man or woman knows that they are lacking in necessary readiness for marriage, like the aptness to be unfaithful, they should not ruin someone else's life. Many people are not cognizant enough to be so considerate.
The decrease in societal morals has weakened the family, from parents to children, and caused these once important institutions (marriage and family) to become weaker.
