Sleep

Sleep is a naturally recurring state of mind characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings. It is distinguished from wakefulness by a decreased ability to react to stimuli, but is more easily reversed than the state of hibernation or of being comatose. Mammalian sleep occurs in repeating periods, in which the body alternates between two highly distinct modes known as non-REM and REM sleep. REM stands for "rapid eye movement" but involves many other aspects including virtual paralysis of the body.

During sleep, most systems in an animal are in an anabolic state, building up the immune, nervous, skeletal, and muscular systems. Sleep in non-human animals is observed in mammals, birds, reptiles, amphibians, and fish, and, in some form, in insects and even in simpler animals such as nematodes. The internal circadian clock promotes sleep daily at night in diurnal species (such as humans) and in the day in nocturnal organisms (such as rodents). However, sleep patterns vary widely among animals and among different individual humans. Industrialization and artificial light have substantially altered human sleep habits in the last 100 years.

Crying

Crying is the shedding of tears in response to an emotional state. The act of crying has been defined as "a complex secretomotor phenomenon characterized by the shedding of tears from the lacrimal apparatus, without any irritation of the ocular structures". A related medical term is lacrimation, which also refers to non-emotional shedding of tears. Crying is also known as weeping, wailing, whimpering, and bawling.

For crying to be described as sobbing, it usually has to be accompanied by a set of other symptoms, such as slow but erratic inhalation, occasional instances of breath holding and muscular tremor.

A neuronal connection between the lacrimal gland (tear duct) and the areas of the human brain involved with emotion has been established. There is debate among scientists over whether or not humans are the only animals that produce tears in response to emotional states.Charles Darwin wrote in The Expression of the Emotions in Man and Animals that the keepers of Indian elephants in the London Zoo told him that their charges shed tears in sorrow.

Reflexive pronoun

In language, a reflexive pronoun, sometimes simply called a reflexive, is a pronoun that is preceded or followed by the noun, adjective, adverb or pronoun to which it refers (its antecedent) within the same clause.

In English specifically, a reflexive pronoun is a pronoun that ends in self or selves, and is an object that refers to a previously named noun or pronoun. Reflexive pronouns take the same forms as intensive pronouns: myself, yourself, himself, ourselves, itself, themselves, yourselves

In generative grammar, a reflexive pronoun is an anaphor that must be bound by its antecedent (see binding). In a general sense, it is a noun phrase that obligatorily gets its meaning from another noun phrase in the sentence. Different languages have different binding domains for reflexive pronouns, according to their structure.

Origins and usage

In Indo-European languages, the reflexive pronoun has its origins in Proto-Indo-European. In some languages, the distinction between the normal object and reflexive pronouns exists mainly in the third person: whether one says "I like me" or "I like myself", there is no question that the object is the same person as the subject; but, in "They like them(selves)", there can be uncertainty about the identity of the object unless a distinction exists between the reflexive and the nonreflexive. In some languages, this distinction includes genitive forms: see, for instance, the Danish examples below. In languages with a distinct reflexive pronoun form, it is often gender-neutral.

Britney Spears

Britney Jean Spears (born December 2, 1981) is an American singer and actress. Born in McComb, Mississippi, and raised in Kentwood, Louisiana, she performed acting roles in stage productions and television shows as a child before signing with Jive Records in 1997. Spears's first and second studio albums, ...Baby One More Time (1999) and Oops!... I Did It Again (2000), became international successes, with the former becoming the best-selling album by a teenage solo artist. Title tracks "...Baby One More Time" and "Oops!... I Did It Again" broke international sales records. In 2001, Spears released her self-titled third studio album, Britney, and played the starring role in the film Crossroads (2002). She assumed creative control of her fourth studio album, In the Zone (2003), which yielded the worldwide success of the "Toxic" single.

In 2007, Spears's much-publicized personal issues sent her career into hiatus. Her fifth studio album, Blackout, was released later that year, and spawned hits such as "Gimme More" and "Piece of Me". Her erratic behavior and hospitalizations continued through the following year, at which point she was placed under a still ongoing conservatorship. Spears's sixth studio album, Circus (2008), included global chart-topping lead single "Womanizer". Its supporting tour The Circus Starring Britney Spears was one of the highest-grossing global concert tours in 2009.
