Why do people get fat after marriage?

Well, I don't think that happens all the time. We pay more attention to overweight people than we do thin people or couples. I think it simply because as we get older, our metabolism slows, it gets harder to exercise, and if you are a woman, or even a man, when you cook for a whole family, you are apt to gain weight. Especially if you have children, a person is apt to get whatever meals are quick, which include fast food. So the quality of your own health disingrates into being there for your family, working a lot to pay the bills (watch those cafeteris and vending machines), in addition to just finding time to exercise. I must note that I am a single girl in my mid twenties, so this all just a theory born of observation and interesting conversations. : )
