Backpacks

Backpacks are very interesting creatures. They are a very diverse family of objects that assist with life, namely in the area of aiding human beings with the transportation of heavy and/or numerous objects without taking up our hands. But on the other hand, if you overload your backpack it can lead to problems. The way the backpack hangs off of one's shoulders places a large amount of stress on the lumbar (lower) region of your back. And consequently the larger the load you place in the backpack the more stress you place on that lumbar region. And also, the more stress you place on that region, the more likely you are to develop lower back problems in the future of life. There are also many subdivisions in the backpack family. You have your mesh ones, clear ones, sporty ones, roller ones, and many different other kinds besides that. And if you don't want to have those lower back problems, then a suitable alternative is the messenger bag, which you sling across your body and over one shoulder. The only downside to the messenger bag is the fact that you have decreased storage space. But on the other hand, you don't get those pesky back problems. So there you have it, backpacks are great ways to transport your heavy items (i.e. textbooks, laptops, little babies), but be careful and don't abuse the carrying power granted to you by these wondrous devices.
