In a new quilt the cotton is not compressed and as such it encloses more air which is bad conductor of heat. Therefore, it does not allow heat to pass.
As strange it may sound, both leeches and blowfly maggots are used occasionally in the field of medicine. The U.S. federal government’s Food and Drug Administration considers both bugs “approved medical devices,” the first live animals to be called that name. Maggots are used to eat dead tissue, thus helping to kill bacteria, clean open wounds, and stimulate healing. Leeches suck out excess blood from the body, and their saliva contains a powerful blood thinner. About 5,000 clean, laboratorygrown maggots are delivered to hospitals across the United States every week.
Haircuts don’t hurt because your hair is not alive. Hair is made out of a protein called keratin. Only the root of the hair—the part that grows inside the skin on your head from tiny holes called follicles—is alive and growing. So if you pluck out a hair by the roots, it hurts. But trimming or cutting your hair is painless. And that is also the same reason why it doesn’t hurt to trim your fingernails or toenails, which are also made of keratin. And because fingernails grow faster than toenails, you need to trim them more often!
The expression grass widow originated hundreds of years ago in Europe where summers were unbearably hot. Because grass was scarce in the lowlands, husbands would send their wives and children, along with their resting workhorses, up into the cooler grassy uplands while they stayed in the heat to till the land. It was said that both the wives and horses had been “sent to grass,” which gave us the expression grass widows.
The temperature may fall below 00C during cold frosty nights which converts the water inside the pipes into ice, resulting in an increase in volume. This exerts great force on the pipes and as a result, they burst.
Motion sickness happens when your body is feeling the sensation of movement. This can happen when you are riding in a school bus, sailing on a boat, or riding in the backseat of a car. When you are reading a book, your eyes do not see the movement, which confuses your brain and causes some people to feel sick. If you get car sick, the solution is to look out the window, not down at your book, so your brain and body will be in sync.
The Statue of Liberty stands for many of the nation’s most cherished ideals: freedom, equality, and democracy. Perhaps most importantly to the millions of immigrants for whom the statue was one of their first sights of the United States, it stands for the ideal of opportunity—the chance to begin a new life, in a new land. While their lives in the United States were frequently difficult, for millions of immigrants America offered the chance to escape from grinding poverty and abusive governments in other lands. Standing in the midst of New York Harbor, the point of entry into the United States for so many immigrants arriving on ships from other countries, the Statue of Liberty has been a powerful symbol of opportunity for more than 100 years.
A poem called “The New Colossus,” written by Emma Lazarus, was mounted on the statue’s pedestal in the early 1900s. Its famous lines include these words that Lazarus imagined Lady Liberty to be saying: Give me your tired, your poor, Your huddled masses yearning to breathe free, The wretched refuse of your teeming shore; Send these, the homeless, tempest-tost to me, I lift my lamp beside the golden door!
During the Second World War, airmen introduced the term “he bought the farm” after a pilot was shot down. The expression caught on with all the armed services and meant that if you gave your life for your country, your impoverished family would receive insurance money for your death, which would help pay off the mortgage on the family farm. Death for your country meant you were “buying the farm” for your parents.
The classic tale of Dorothy in the land of Oz came from the imagination of L. Frank Baum, who made up the story for his son and a group of children one evening in 1899. When a little girl asked him the name of this magical land with the Scarecrow, Tinman, and Cowardly Lion, he looked around the room for inspiration. He happened to be sitting next to a filing cabinet with the drawers labelled “A-G,” “H-N,” and finally “O-Z,” which gave him a quick answer: “Oz.”
