¡¡¡¡Are you carrying too much on your back at school?I¡¯m sure lots of children of your age will say¡°Yes¡±£®Not only the students in China have this problem, but children in the USA also have heavy school bags£®

¡¡¡¡But how much is too much?Doctors say students should carry no more than 10% to 15% of their own body weight£®Scott, a back doctor, said children under Grade 4 stay with 10%£®But it¡¯s also important that older children don¡¯t stay with over 15%, because their bodies are still growing£®¡°Children are losing their balance(ƽºâ)and falling down with their school bags,¡±he said£®
