Mostly what kind are the backpacks do girls use. Also if I packed a lunch for High School should I put in a bag or a lunch box? Will be in HS this end of August!
yeah I should get a Thomas the Tank Lunch box.. JK!



Answer
*laughs* I went through this when I went to college. I decided that backpacks weren't the thing for a university girl and ditched the back pack and went for a book bag.

Just one thing and I am not sure how your new school will be but make sure you get a locker or have a locker that you're sharing with otherwise those books can be a pain to carry and tote around. My old high school was so picky about giving out lockers it wasn't even funny. I couldn't even get a locker. So I ended up with one of those backpacks with wheels so I ended up wheeling my books around, much easier than wearing those books on your back and those books are heavy.

How do women from other countries carry so much weight on their heads?

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..
