How has the world changed since you were a child? Are these changes good or bad?

To me the world has changed a lot from when I was a child. Everything, for example: the people I hang out with, social conversations based on the subjects, events to activities that I used to love doing and now not even thinking about them anymore. Just life itself has changed so much. Things don't seem like how they would be or when doing something theres no more feeling of liking or the sensation's of wanting to go at it anymore. To me I just say that I'm getting too old and this is the way I'm suppose to feel. But a part of me says that I'm wrong so now a days I just don't think about it at all. Or maybe it's just that I don't do the same thing's I used or would be doing if I were still a kid. I would say that all the changes that had happened so far are good and bad. Good because I know that I'm moving along in life and that thing's like this do happen and I know how to cope with it. Bad because it's the past times that were the funnest and I don't want to let that go either. But come to think of it thing's change all the time and most of the time you can't do anything to differ those changes. The way I see it the more you think about it and try to reverse or fight the changes in your life the more hurt and trouble your going to cause to yourself. Just don't let the changes around effect you.
