Legal case
A legal case is a dispute between two parties that is resolved by a court or other legal process. A legal case may be either civil or criminal. The decision of a court is usually published in one form or another for later reference. In countries like the United States which have a common law system, decisions by a higher court are binding on lower courts when the facts and issues are similar. Stare decisis, or the concept of precedent, means to follow cases that were decided earlier when judging the current case.
Nasal hair
Nasal hair are small hair-like cells in the nose. Most of them can be found near the nostrils. The purpose of these hairs is to act as a filter, keeping dust and dirt out of the nasal passages. They also draw liquid mucus up from the epithelium by capillary action. In that way, they help to maintain humidity in the air passages and stop them from drying out. The hairs trap moisture as air is breathed out. The evaporation of trapped moisture on the hairs increases the humidity of air as it is breathed in. Note that nasal hair is different from the cilia found in the nose, which are part of the olfactory system.
Some cultures consider nose hair coming out from the nostrils to be ugly. The increased growth of nasal cilia with age (particularly for men) is often a source of anxiety and embarrassment. A number of devices have been sold to trim the nose hair, including small rotary clippers and attachments for electric shavers. However, given the role of nasal cilia, many doctors recommend trimming them lightly, if at all. There is evidence that the movement in the ciliar slows down with age. This may be the reason that old people have more respiratory infections.

Willis Tower
Willis Tower is a skyscraper in Chicago, Illinois. Sears, Roebuck and Company paid for it to be built in August 1970. The building was finished in 1973. It was the tallest building in the world from 1973 to 1996. It has 110 levels. From the ground to the roof it is tall. It was designed by Fazlur Khan and Bruce Graham.
Willis Tower is the second-tallest building in the United States. It is the eighth-tallest freestanding structure in the world. It is the second tallest skyscraper in the Americas. It is one of the most popular tourist destinations in Chicago. More than one million people visit its observation deck every year.
Until July 16, 2009, the building was called Sears Tower. It was renamed after the Willis Group bought it.
In 1969, Sears, Roebuck & Company was the largest retailer in the world. It had thousands of workers in offices in the Chicago area. Sears managers decided to put all of those workers into one building. They wanted of space. Sears hired architects Skidmore, Owings & Merrill (SOM) to design one of the largest office buildings in the world. Architect Bruce Graham and structural engineer Fazlur Khan designed the building.
Sears and the City of Chicago approved the design. Steel was transported from South Chicago. The first steel was put in place in April 1971. The tower was completed in May 1973. It cost about US$150 million to build. That is equivalent to $800 million in 2014.
The building was built with a fire sprinkler system, even though it wasn't required at the time. There are about 40,000 sprinkler heads in the building. The sprinkler system cost $4 million.
In February 1982, two television antennas were added to the tower. That made the building tall. On June 5, 2000, the western antenna was made longer to improve reception of local NBC. That made the overall height
Before Willis Tower was completed, the tallest building in the world was the World Trade Center. In 1996, the Petronas Twin Towers in Kuala Lumpur, Malaysia became the world's tallest buildings.
The building's name was changed to Willis Tower in July 2009 after the Willis Group bought the skyscraper. "Time" magazine called the name change one of the top 10 worst corporate name changes. An online petition was created to change their decision. The naming rights issue continued into 2013. It began when a news reporter of the "Chicago Tribune" said in 2013 that "We're stubborn about such things. This month marked four years since the former Sears Tower was re-christened Willis Tower, and the new name has yet to stick."
In 2015 the Blackstone company bought the building. In 2017 it began an extensive repurposing of the lower part of the building.
Skidmore architects designed Willis Tower to have large floors of in the lower part of the building. They got the idea for the design from an advertisement for a package of cigarettes.
From the ground to the top of the taller antenna, Willis Tower is tall. It leans about towards the west because of the unequal loads on its foundation. Willis Tower is the second tallest skyscraper in North America. The observatory elevators in the tower are the fastest in the world at per minute. With clear weather, four states can be seen from the observation deck: Michigan, Indiana, Illinois, and Wisconsin.
On November 8, 2013, architects in Chicago and New York City started talking about the height of the One World Trade Center. They were saying that Willis Tower might be taller. On November 12, it was confirmed that One World Trade Center is taller than the Willis Tower.
Willis Tower has an observation deck. It is called the Skydeck. It opened on June 22, 1974. It is on the 103rd floor of the building. It is high. It is one of the most famous tourist attractions in Chicago. The observation deck is the highest public viewing area in the United States. Tourists on the Skydeck can feel the building moving on windy days. They can see the plains of Illinois and across Lake Michigan. Elevators take tourists to the top in about 60 seconds. People on the elevator can feel air pressure changes during the ride.
