Have a healthy lifestyle
As we all know, health is very important. Only when we are healthy can we study w ell and enjoy life.
However, many teenagers don't pay any attention to their health, especially during the holiday. And they spend too much time watching TV, playing games and chatting on the Internet all night, which is bad for their health. First, this may make them get near-sighted. Besides, their bodies be come much weaker. Thirdly, they will lose the chance to communicate with others face to face as they never go out, which may have a bad effect on their mental health.
In my opinion, they should spend less time in front of the TV or the computer. Go out to take some exercises, play some sports and visit some and have a healthy lifestyle.
