We heavily rely on technology for our daytoday lives. There are the social media apps, such as Facebook, Twitter, where we are able to see into the lives of everyone around us. There are other more useful apps like Google Maps where you can use a GPS to get from one place to another. It is no wonder that we are constantly looking down at our phones and other devices. And, that is a problem. What I really dislike is that younger and younger children are using technology. Instead of playing outside with friends, they are playing on iPads, iPods, or video games. Instead of having little games or books, children now have electronic devices to use to distract them even if waiting at doctors39。 We are a society based on technology.
