    Too many Americans watch too much television. Americans maybe watch more TV than any other people in the world. This is not a good thing. Because of TV, Americans are getting too heavy and spend less time with their friends.

    Many American students watch TV between twenty and sixty hours a week! That is very bad for their study. When they watch too much TV, they have less time for exercise, study and sleep. Most people that watch a lot of TV eat at the same time. This is very bad because they eat too much and get too heavy.

    It is better to watch just a little bit of TV a day. Thirty minutes to one hour is enough. If you have much free time, it is a good idea to read a book, play sports or spend time with your friends and families. Studying is also a good way to spend your free time.
