A person naturally stands in a fashion that places there center of gravity over there feet and just forward of there ankles. For example, It is common to see many pregnant women leaning back because of the extra weight of the fetus in the front of there body. For the same reason back packers lean forward to counter act the extra weight of the pack on there back. How far one leans is determined by how heavy the pack is. :)
Because the fulcrum where the vast majority of the weight (load) is resting is in the lower back area, by leaning forward the overall centre of gravity of the individual (the person + load) is thereby centred, resulting in less strain on the lower back. In addition, if standing up straight the person becomes 'back heavy' making it harder and slower to walk.

Can a heavy backpack make you shorter?
Using a backpack will not make you grow taller. Factors that directly affect height are genetics and diet. Things that influence muscular and skeletal development will affect posture and height or apparent height. Excessive or awkward weight carrying, whether in a backpack or otherwise, could affect these, but so can toxins in the environment, poor posture, lack of exercise and arthritis. Backpacks, when fitted correctly, can be used to help carry weight evenly and reduce stresses on the body.

Make Sure Your Kid's Backpack Is The Right Size?
When buying a backpack for a kid, make sure you get one that's the right size for his or her capabilities. Just buying the largest backpack you can find could result in your little one carrying a load with weight that's not properly distributed. Carrying a heavy load all at the base of the spine is no good for anyone's back, and it's not a great start to any school day. Look for one with pockets and zippers that allow your child to distribute the weight vertically as well as horizontally in the pack, or a smaller bag that will prevent overloading.
