Science has given us many important discoveries. The polio vaccine, the use of penicillin, and now this groundbreaking work on backpacks:
Many teens carry school backpacks that exceed 10 percent to 15 percent of their body weight, which puts them at risk for back pain and related disorders, a new study says.
The threat posed by the heavy weight is made greater by the fact that most teens don’t get enough exercise, according to the researchers.
The study included more than 1,400 students, aged 12 to 17, in 11 schools in a province in northwestern Spain. The teens were first weighed with the backpack they normally carry to school and then weighed again without the backpack.
I did not see this one coming. Next we will hear that sitting too much could be deadly.
