For a long time I have observed how many of us carry many school supplies to school to write, trace, cut, underline, color ... There are so many things that we carry that the weight is a lot.

 Introduction.

How can we avoid carrying so many things? How can we reduce the weight? How can we get our objects more easily? ... All this has an answer, the Rucal. Reduces the weight and space of 4 objects.

I will explain to you how the abuse of the weight on your back affects your health, how Rucal will benefit you, the correct way of use and much more.

The Weight and it’s Consequences.

Backpacks loaded with excess weight and can cause some major health problems.

First, the spine is made up of 33 bones called vertebrae, and between the vertebrae are discs that act as natural shock absorbers.

When you incorrectly place a large weight on your shoulders, such as a backpack full of books and other objects, the force of the weight can pull you back. To compensate, you may lean forward at the hips or hunch your back; This can cause the spine to compress in an unnatural way. It will affect you over time with herniated disc, severe back pain or other problems in your spine.

Those who carry heavy backpacks sometimes also compensate for the extra weight by leaning forward; Over time, this can cause the shoulders to round and the upper back to hunch. Due to the heavy weight, there is a possibility that you will develop shoulder, neck and back pain.

If you carry your backpack on only one shoulder or if you carry your books in a messenger bag, you may end up leaning to one side to compensate for the extra weight. You could develop pain in your upper and lower back, and strain your shoulders and neck.

Very bulky or heavy backpacks don't just cause back injuries. People carrying very large backpacks generally do not realize how much space they take up and may hit others with their backpacks when turning or moving in tight spaces, such as school bus aisles. Students also hurt themselves when they trip over large backpacks or when they are dropped on them.

In addition, the use of heavy backpacks changes the way you walk and increases the risk of falls, especially on stairs or other places where the backpack causes you to lose your balance.

For all this, we must reduce weight and backpacks full of objects to be healthier.

Benefits of Rucal.

Rucal is an invention that will allow you to reduce 4 objects from your backpack, they are: ruler, scientific calculator, conveyor and clock. These four objects are super necessary for young people, teenagers, engineers, architects, mechanics ... professions in general and university students.

Doctors and physical therapists recommend that people carry no more than 10-15% of their body weight in their backpacks. That means if you weigh 120 pounds, your backpack shouldn't weigh more than 12 to 18 pounds (5 to 8kg).
