在街上打機, 對身體有何影響?

長期打機is hurt your eyes,that your eyes will fell tired easy,and take a short-sight.
so your eyes will 勞損最多
if 小孩小們一路打機, 一路走路,that the accident will occur easy. for example,the theif will stole their psp or nds on the street.
在心理素質上,小孩小們很大機會過度沉迷打機,形成一種病態.
對家人的關係,容易有火花,因為學業會有所下降.
I suggest the sport which are swimming,basketball and table tennis.

Tennis is good~~~~~~~
