Social network is where people communicate with others. Usually people are stuck in their house and doesn't know what to do, does that ever happened to you? It didn't happened to me, but it must happened to someone else. If you're a kid and your parents let you go on social networks, you're going to have to control yourself don't go on that much.
When your parents won't allow you to go on social network, you can go out and play sports. Either you're a kid, adult, or a senior you can still play sports. To play sport you don't need to be 13 and older you can play any time you want, even when you are a toddler.
