Disease and poverty exist all over the world. The areas with the most disease and poverty are countries in sub-Saharan Africa and the Asia-Pacific region. In these areas, people do not have enough food to eat, water to drink, or money to live.
They have diseases like AIDS, which weakens the immune system, and cholera, an intestinal infection. In the United States, about 33 million people live in poverty, according to government statistics. Almost 12 million of these people are children, and about 3.5 million were age 65 or older.
Much of what you need to know to live successfully as an adult does not come naturally— it has to be learned and studied and memorized. Children learn to speak nathandy urally, for example, by listening to those around them, but reading and writing must be specifically taught. The complicated process of learning the alphabet and the sounds it represents, putting letter sounds together to make words, and learning the meaning of words in order to read and write are skills that only come with special effort. Knowing how to figure out problems that involve numbers, and learning how the world is run or how nature works are important things to learn, too. Although your parents might be able to teach you these things, they would need many hours each day to do it. Most parents work outside the home and wouldn’t have the time to give proper instruction (although some kids are “home schooled” by their parents instead of going to school).
In the United States, a public school system provides years of free education for all children. Teachers, who are specially trained to know what children should learn, and how, and when, are the people who do the job. To ensure that children learn what they need to, state governments now require that all children go to school for a certain number of years (usually until age 16). Kids who skip school a lot can find themselves in court. (Children who go to private schools or whose parents have received special permission to teach them at home are exceptions.)
The femur, or thighbone, is the biggest bone in the body. The average femur is 18 inches (45.72 centimeters) long. The longest bone ever recorded was 29.9 inches (75.95 centimeters) long. It was from an 8-foot-tall (2.45 meters) German who died in 1902 in Belgium.
The stirrup (also called the stapes) in the middle ear is the smallest bone in the body. A tiny, U-shaped bone that passes vibrations from the stirrup to the cochlea, it weighs about 0.0004 ounces (0.011 grams) and can measure just one-tenth of an inch.
In 1880, the strong-willed senator John Sherman was testing the water for a presidential nomination. He slipped out of Washington but was followed to his Ohio farm by a reporter who found the senator talking with a high-ranking party official while standing near a fence.
When the reporter asked what they were doing, the response, “We’re mending fences,” gave him his headline, and it became a new phrase for healing relationships. Within a democracy, what are the fourth and fifth estates?
In 1814, after a night in a pub, Francis Scott Key was taken prisoner during the war between Canada and the United States. When he saw the American flag still flying over Fort McHenry he was inspired to write his famous lyrics with one particular barroom song, “To Anacreon In Heaven,” still in his mind.
And so “The Star Spangled Banner” was written to the tune of a traditional old English drinking song.
Your spine, also called the backbone, runs down the length of your back from the base of your neck to your pelvis. The spine has 25 joints connecting 33 individual bones. (The bottom four bones of the spine are fused together to form the terminal vertebrae called the coccyx, or tailbone—and the five bones above that are fused together to form the sacrum. They are caged within the bones of the pelvis.) Each bone in the spine is called a vertebra and they are grouped together to perform specific tasks.
The spine supports your head, lets you twist and bend, and holds your body upright. It also protects the spinal cord, a large bundle of nerves that sends information from your brain to the rest of your body.
