i dont think getting married or having kids is a reason to stop going clubbing. i do think it is a time to become more responsible. for example, instead of going out 3 nights a week, once a month. it has to do with your priorities. if you are 40 years old and dont have a child to support, i see no reason to suddenly stop going because of your age. when i lived in miami, i met a couple that lived in west palm beach, the had 2 children. they still liked to party though. we talked about it and they told me that they would go out once every few months, party hard, and then get back to their lives. they had someone take care of their children for the night and stayed in miami at a friends house so they wouldnt have to drive all the way home after partying all night. its not about the age you are, but how u can or if you can fit it into your life with out making it a distraction. that is true even if you are 21 years old, clubbing is a thing to do to have fun, it shouldnt become the only thing you do....
