kids backpacks on wheels 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..

How much money to eat at disney for 7 days?
Kenneth B
2 adults and 2 children (3 and 1) are going to Disney World Oct1-8, 2010. We are staying in our Timeshare which has 2 bedrooms and a full kitchen. We will eat Breakfast each day at the Timeshare. Lunch will be trickey. Can we take backpacks to disney parks with water and snacks in them? Dinner we would like to eat out a few nights. Any suggestions. Total money needed?
Answer
Yes, you can take food and bottled water into the parks; there are a few restrictions---coolers/backpacks can't have wheels, and must be smaller than 24" (61 cm) long x 15" (38 cm) wide x 18" (46 cm) high. You can't take food that requires heating or glass containers (except for baby food.)
How much you spend on food is up to you--generally a counter-service meal is around $10--$11 with a drink, kid's meals are around $5. You can see Disney menus online. If you ate 1 meal like that per day in the parks, 2 adults and 1 kid's meal would be around $25 or, $175 for 7 days. Of course that depends if you want soda with every meal, can split the kids meal and supplement with snacks, etc. I do suggest trying at least one of the restaurants in Epcot. Lunch is usually cheaper than the dinner menu. Most of the pavilions have a counter-service restaurant too, so you can try the cuisine without a full sit-down expensive meal. I like the ones in Japan, Morocco, and Norway, but not everyone digs hummus or salmon and egg sandwiches.
Restaurants around Orlando offer some good bargains. How much you spend is again up to you, an all-you can eat buffet at the Ponderosa will cost much less than one with crab legs and lobster.
