Passage 73
Are you carrying too much on your back at school? You’re not alone. Back experts in the United States are worried that young students are having back and neck problems as a result of carrying too much in their backpacks (schoolbags).
“It hurts my back when I run,” said Oberlin Reyes, a student in Virginia. “It’s hard to get up the stairs with my backpack, because it’s too heavy.”
Oberlin is among students whose backpacks were weighed for a week in a recent study.
They had regular backpacks with two straps (带子) to carry them, but a number of students with heavy loads had switched to rolling backpacks (which have wheels and can roll on the ground).
Shirley Park, whose backpack weighed 10 kilograms, said she changed to a rolling backpack because she was starting to have back pain.
