Nowadays, teenagers have changed considerably in comparison to the teens in the past in how they spend their free time. This is a technology generation. For teens in todays world, mobile phones, the Internet, and TV are essential parts of their everyday life. Most teenagers prefer watching TV and surfing the Internet to reading books. They dont like reading because watching TV is easier and they dont have to use their own imagination. Teenagers prefer to spend free time in front of a computer rather than to do physical activities such as playing football, riding bikes or going swimming. According to a recent study, teenagers growing up in the 1970s and 1980s enjoyed more than two hours of outside play each weekday, and a further nine hours at weekends, whatever the weather. However, today's teens play outside for just over an hour each weekday, and fewer than five hours on Saturdays and Sundays. Teens now often communicate to their friends by instant messages instead of talking face-to-face. When they want to share their feelings or some private thoughts, they will post them on Facebook. This makes it easier to get comments or receive encouragement from friends. Keeping a diary is out of date now. Teens now spend more time meeting friends in places like fast food restaurants or cafes. They like to eat fast food, greasy food and sugary drinks more than home-cooked meals. This leads to obesity. In conclusion, the lifestyle of teenagers has changed a lot compared to the past. Parents should encourage their children to play outdoors more. This helps them not only stay active and healthy but also socialize with friends as well as create treasured childhood memories. 1. What is NOT mentioned as the differences among teens now and then?
