The FaceBook
People some times argue about internet,electronics devices and sometimes social networks. They like to to talk about the negative and the positive points of this stuffs, the effects that those thing can give to us, principally the effects at the children and teenagers, and because of that, we want to talk about something we are use to use almost of time this days, the FaceBook, an social networks for those who do not know what FaceBook, and the effects that it's causes at the teenagers, the good effects and the bad side of it hehehe.
In the first place, we have the negative effects of use of this social network, some studies , as "Poke Me: How Social Networks Can Both Help and Harm Our Kids", made by American Psychological Association.To being with, they showed that the excessive use can let the person have "narcissistic tendencies", depression and worry, those who use the social network can show antisocial comportment, he can become more aggressive , have manias and it would let the person have health problems. The abuse of the network can have bad effects at grades and the academic life.
On the other hand, we have the good side of the use of the network, for instance, it can help introverted teenagers to socialize and meet new people, make news friends, it can help they to know how to socialize; the use of the network can be use too as a education too, it can show new and funnies ways to teach the teenagers.
In conclusion, the use of the FaceBook as another social network can have positive and negatives effects at the teenagers and other peoples, but the secret to avoid some negatives effect or just for minimize them is to no abuse the social network, use it with moderation.
