The Combat Fitness Test is a physical fitness test of the United States Marine Corps, and is used in complement to the USMC Physical Fitness Test.
 The British Army formerly used a test of the same name which is currently known as the Annual Fitness Test.
The United States Marine Corps requires that all Marines perform a Physical Fitness Test (PFT) and a Combat Fitness Test (CFT) once per calendar year.
 Each test must have an interval of 6 months (same standards apply for reservists).
 The PFT ensures that Marines are keeping physically fit and in a state of physical readiness.
 It consists of pull-ups or push-ups, crunches and a 3-mile run.
A test or examination (informally, exam or evaluation) is an assessment intended to measure a test-taker's knowledge, skill, aptitude, physical fitness, or classification in many other topics (e.g., beliefs).
 A test may be administered verbally, on paper, on a computer, or in a confined area that requires a test taker to physically perform a set of skills.
 Tests vary in style, rigor and requirements.
 For example, in a closed book test, a test taker is often required to rely upon memory to respond to specific items whereas in an open book test, a test taker may use one or more supplementary tools such as a reference book or calculator when responding to an item.
 A test may be administered formally or informally.
 An example of an informal test would be a reading test administered by a parent to a child.
 An example of a formal test would be a final examination administered by a teacher in a classroom or an I.Q. test administered by a psychologist in a clinic.
 Formal testing often results in a grade or a test score.
 A test score may be interpreted with regards to a norm or criterion, or occasionally both.
 The norm may be established independently, or by statistical analysis of a large number of participants.
Masters swimming is an organized program of swimming for adults.
 U.S. Masters Swimming (USMS), founded in 1970, is a nonprofit membership national governing body.
 The program began when the first National Masters Swimming Championships were held on May 2, 1970 at the Amarillo Aquatic Club pool with a few dozen swimmers.
 Captain Ransom J. Arthur, M.D., a San Diego Navy doctor, had persuaded John Spannuth, President of American Swimming Coaches Association, that the event would give older swimmers (ex-competitors and beginners) a goal for keeping physically fit.
 Arthur's mission of encouraging adults to improve fitness through swimming has grown over the years into a nationwide organization that currently includes more than 60,000 adult swimmers.
LAN eXtensions for Instrumentation (LXI) is a standard developed by the LXI Consortium, a consortium that maintains the LXI specification and promotes the LXI Standard.
 The LXI standard defines the communication protocols for instrumentation and data acquisition systems using Ethernet.
 Ethernet is a ubiquitous communication standard providing a versatile interface, the LXI standard describes how to use the Ethernet standards for test and measurement applications in a way that promotes simple interoperability between instruments.The LXI Consortium ensures LXI compliant instrumentation developed by various vendors work together with no communication or setup issues.
 The LXI Consortium ensures that the LXI standard complements other test and measurement control systems, such as GPIB and PXI systems.
While fitness is defined as "the condition of being physically fit and healthy",
Documentation testing is part of non-functional testing of a product.
 It may be a type of black box testing that ensures that documentation about how to use the system matches with what the system does, providing proof that system changes and improvement have been documented.
 Documentation testing includes the plans, results, and testing of a system or system component.
 It includes test case specifications, test plans, test procedures, test reports, and test logs.
 It is about the testing of all the documents stating, defining, explaining and reporting or validating requirements, procedures followed and results.
 Documentation testing starts with the beginning of the very first software process to be most cost effective.
 Documentation testing includes checking the spelling and grammar to review any ambiguity or inconsistency between what functionality it performs and what it is supposed to do.
The chasquis (also chaskis) were the messengers of the Inca empire.
 Agile, highly trained and physically fit, they were in charge of carrying the quipus, messages and gifts up to 240 km per day through the "chasquis" relay system.
 "Chasquis" were not just messengers (those were young boys who were just used to pass along basic information);) the "chasquis" were trained to be able to read and translate the khipus to each other and higher authorities.
 Not only were they used to transport oral messages, but they also helped the inspector general, the Sapa Inka's brother, keep track of the people in the empire.
Special Forces: Ultimate Hell Week is a British reality television series where physically fit civilian contestants are put through special forces style selection exercises.
 Each episode features an instructor and exercises from a different force, and contestants either withdraw voluntarily, are medically withdrawn, or are dismissed for poor performance.
Thriller is a viral video featuring the CPDRC Dancing Inmates of a high-security penitentiary.
 In 2007, the inmates of Cebu Provincial Detention and Rehabilitation Center (CPDRC), a maximum security prison in Cebu, the Philippines, imitated the zombie dance featured in the music video of Michael Jackson's "Thriller".
 The footage, uploaded onto video-sharing website YouTube, became a viral video.
 The idea behind the dance came from the prison's chief, Byron F. Garcia.
 Garcia first conceived the idea of exercising as an enjoyable way of keeping the prisoners mentally and physically fit.
 Music was then added to provide additional motivation.
 The convicts marched and danced to several songs, including "In the Navy" and "Y.M.C.A." by the Village People.
