other, most of us are texting on our smart phones. Teenagers are always texting, and all this messaging
can give us Teen Texting Tendonitis which makes the hands, back and neck hurt.
Having a smart phone makes teenagers want to spend all day talking or texting, instead of doing things
that we are supposed to do, such as our homework. Teens who spend too much of their time with their
phones are always tired; they also start having other problems. In some cases, they may have headaches.
This happens because most teens keep their smart phones near them while sleeping, so that they can
answer texts and calls. They often feel they have to be available around the clock.
Using texting all the time as a way of communication can also make us teens worry a lot. Answering all
my friends' texts can make me happy, because it makes feel popular. However, if any of my friends takes
a long time to send back a text, then I can feel very sad.
