Facebook Addictions

Over the past few years a new social networking site called Facebook has gotten so popular in the U.S.  I think that the U.S. population has gotten some say addicted to Facebook.  I say this because I did some research and I found that more than 40% of the U.S. population owns at least one live Facebook account.  I also read up on that more than one million people sign on an off Facebook every day.  That means over seven million people go on Facebook in a week!!
I myself own a Facebook account and I go on once or twice each day.  But I have some friends that stay on for three hours straight.  Another interesting fact I read up on is that it is very bad to stare/look at a computer or TV screen for a certain amount of time.  Also I have realized that kids who stay on Facebook to long get lazier and lazier until it gets to the point where they never step foot outside.  I understand Facebook is a fun website to communicate with your friends and play games, but don't spend your whole day on it.  Instead of going on Facebook there are plenty of other fun things you could do, such as go outside and play sports, go to a friends house, or ride your bike.  I'm not saying never use Facebook again, but don't spend your whole day playing games or instant messaging you friends on Facebook.  Please comment and tell me what you think about the growing population of Facebook users.
