Some do, but it's a bit misguided. I guess it depends on your experience with it. For instance, my parents don't get along that well, but they are still married, they are the only ones who could put up with eachother's shit so somehow it works. I don't think marriage should be about compromise, but a lot of the people i see that get married end up being miserable for the most part, hence the divorce rate. Many people feel pressured to get married if they have been dating for a long time, or they feel that they are getting too "old". Legally it makes sense to get married, but emotionally it's a whole other realm. Age should have nothing to do with it, only finding the right person. The more important question to ask is, do people believe in finding the "one"?
