Question

know how to pack things for carrying them on one's shoulders​

Answer 1

Answer:

A backpack that isn't used properly can cause back problems or even injury. Here’s how:

By putting a heavy weight on your shoulders in the wrong way, the weight's force can pull you backward. So people who carry heavy backpacks sometimes lean forward. Because of the heavy weight and this unnatural position, they can develop shoulder, neck, and back pain.
