I think it's not a flat rate or something. Marriage, or copulation, has been the trend of all animals, humans inclusive, since we existed. Society has tried really hard to define how and when marriage should occur, as well as associated ideals with it, but the bottom line is: not everyone is going to get married or in a relationship at the same time as others. Yes,
most people marry in a certain age bracket, but the variation is enormous across the board. I know it's much to do with social and cultural factors, but within a particular society and class, there is a lot of variation. Why? It varies from person to person. Someone may be ready to marry and manage their studies at the age of, say, eighteen while someone who's done with their studies and not even working may still be unprepared. I want to marry when it's the right time for
me, and that can be now or ten years later. People can whine about it all they want: my marriage, my husband, my chocolate.
