I think a woman has to be over 25 yrs of age before marriage. I think maturity and sense of responsibility does not come until around that age. For a man, it should be over 27. Not a good idea to marry in your early 20's. I think by 27 he usually knows what kind of woman he wants to spend the rest of his life. I do not think there is or should be any upper limit to the age for marrying. Any age above what I said is good. As long as you have found a good company for the rest of your life, get married, doesn't matter if you are 30's, 40's, 50's, 60's or 70's. By 80's I think most people start getting ready to go to Heaven. :)
