Customary units in the United States
United States customary units are a system of measurements commonly used in the United States. The U.S. customary system developed from English units which were in use in the British Empire before American independence. Consequently most U.S. units are virtually identical to the British imperial units. However, the British system was overhauled in 1824, changing the definitions of some units used there, so several differences exist between the two systems.
The majority of U.S. customary units were redefined in terms of the meter and the kilogram with the Mendenhall Order of 1893, and in practice, for many years before. These definitions were refined by the international yard and pound agreement of 1959. The U.S. primarily uses customary units in its commercial activities, while science, medicine, government, and many sectors of industry use metric units. The International System of Units (SI), the modern form of the metric system, is preferred for many uses by the National Institute of Standards and Technology (NIST).

The system of imperial units or the imperial system (also known as British Imperial) is the system of units first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The system came into official use across the British Empire. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement; however some Imperial units are still used in the United Kingdom and Canada.
War on Terror
A common definition of terrorism is the systematic use or threatened use of violence to intimidate a population or government and thereby effect political, religious, or ideological change. This serves as a list and compilation of acts of terrorism, attempts of terrorism, and other such items pertaining to terrorist activities within the domestic borders of the United States.

Hand luggage or cabin baggage (also commonly referred to as carry-on in North America) is the type of luggage that passengers are allowed to carry along in the passenger compartment of a vehicle instead of moving to the cargo compartment. Passengers are allowed to carry a limited number of smaller bags with them in the vehicle and contain valuables and items needed during the journey. There is normally storage space provided for hand luggage, either under seating, or in overhead lockers. Trains usually have luggage racks above the seats and may also, especially in the case of trains travelling longer distances, also have luggage space between the backs of seats facing opposite directions or in extra luggage racks for example at the ends of the carriage near the doors.
Hospitality is the relationship between the guest and the host, or the act or practice of being hospitable. This includes the reception and entertainment of guests, visitors, or strangers.

In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
