Are you carrying too much on your back at school? Back experts in the U. S.A. were worried that young students are having back and neck problems because they are carrying too much in their schoolbags.

"It hurts my back when I run," said Ebelin Reyes, a student in Virginia. "It"s hard to go upstairs with my schoolbag because it"s too heavy."

Students have to carry heavy schoolbags on their backs for a whole week"s study. Ebelin is one of them. They have schoolbags with two straps (带子) to carry them, but a number of students with heavy loads (负荷) have switched to rolling schoolbags. The schoolbags have wheels (轮子) and can roll on the ground. Shirley Park"s schoolbag weighs (重) 10 kilos, and she said, "I"ll change to a rolling schoolbag because I am starting to have back pain."

How much is too much? Experts say that students should carry no more than 10 to 15 % of their own body weight. A few students have had a good idea to lighten the load: less homework.

The year was 1839. Vice (副……) President Richard M. Johnson was in New York City on his way to Philadelphia. He was expected at a meeting at 6:30 that evening. When did he begin his trip? At noon!
