it depends on what time you are getting married... if you are going to marry for the first time at your 35 it's not too good... if by your 20 your were married already 2-3 times it's also not to healthy...
i would agree with gypsy on it.. if by your 40 you are on your 3d-4th marriage, you are all right...
