kids backpacks for school image
jzeb100
The schoo project im doing requires coming up with a solution to help people carry weight that they arent supposed to carry. Average man is supposed to carry 15% of their weight, but many people carry more and backpacks for school kids also cannot hold a lot. Im doing some research and found African woman can hold 70% of their weight on their heads, but how do they do it?
Answer
One reason for the African woman's ability to bear loads effortlessly seems to be her posture. As a girl, she learns to stand so straight that her pelvis and vertebrae line up like a well stacked pile of blocks.
Another reason may lie in her gait. At the beginning of most persons' strides the head bobs up and the body slows; then as the foot moves forward, the head dips and the body accelerates. This bobbing and dipping and accelerating and decelerating requires a lot of effort. But African women put all their energy into moving forward. The vertical motion is absorbed in the bones and soft tissue. Hips bob less than ankles; shoulders bob less than hips; and the head (with its burden) bobs not at all. Thus, while most people bounce along like wagons on egg- shaped wheels, African women move like wagons on round wheels.
I tried putting in some references for you of interesting articles but everytime I do I get ERROR 999!!
Try typing a sentence from above in google to find it. There was also another interesting paper in Nature magazine..

What does a kid need in his backpack for headstart?

My son is 3 and wants to take a backpack to school this year when he starts headstart. What should I put in it, because it isn't actually required to bring one? Any ideas?
Answer
Put a Composition notebook and some crayons. Composition notebooks are pretty cheap and it could make him feel like a big kid going to school with a little notebook to write in. Also the crayons are always fun for kids, I still love them and I'm in high school :D ! Packing a toy would be nice too. Just not his #1 Favorite. If other kids take his favorite or it breaks it would be the end of his world.
