The average weight of a high school student’s backpack is 20 pounds and contains about 6 textbooks. In comparison, the average weight of an ebook reader, capable of holding hundreds of books and instantly accessing hundreds of thousands more, is less than a pound.

Lugging a heavy backpack around for extended periods of time can lead to back pain, shoulder pain, and also bad posture.

So, my question is why aren’t more chiropractors championing the advent of e books!?
