Id, ego and super-ego

Id, ego, and super-ego are the three parts of the psychic apparatus defined in Sigmund Freud's structural model of the psyche; they are the three theoretical constructs in terms of whose activity and interaction our mental life is described. According to this model of the psyche, the id is the set of uncoordinated instinctual trends; the super-ego plays the critical and moralizing role; and the ego is the organized, realistic part that mediates between the desires of the id and the super-ego. The super-ego can stop one from doing certain things that one's id may want to do.

Although the model is structural and makes reference to an apparatus, the id, ego and super-ego are purely psychological concepts and do not correspond to (somatic) structures of the brain such as the kind dealt with by neuroscience. The super-ego is observable in how someone can view themself as guilty, bad, pathetic, shameful, weak, and feel compelled to do certain things. Freud (1923) in The Ego and the Id discusses "the general character of harshness and cruelty exhibited by the [ego] ideal – its dictatorial 'Thou shalt.'"

Blood

Blood is a bodily fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. When it reaches the lungs, gas exchange occurs when carbon dioxide is diffused out of the blood into the pulmonary alveoli and oxygen is diffused into the blood. This oxygenated blood is pumped to the left hand side of the heart in the pulmonary vein and enters the left atrium. From here it passes through the mitral valve, through the ventricle and taken all around the body by the aorta. Blood contains antibodies, nutrients, oxygen and much more to help the body work.

In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains dissipated proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is almost entirely transported extracellularly dissolved in plasma as bicarbonate ion.

To Be (song)

"To Be" is the English title of a Japanese-language song by Ayumi Hamasaki. It was released as the singer's eighth single on May 12, 1999. The song begins "Dare mo ga toorisugite...", and does not contain the phrase "to be" or any other English lyrics.

Information

"To Be" was released less than a month after her first number one single, "Love (Destiny)." Hamasaki's first song to be composed by Do as Infinity composer DAI, "To Be" was unable to reach the top position on the Oricon, unlike its predecessor. Hamasaki re-recorded "To Be" in celebrating her 10th anniversary in the music business in 2008 and it appeared as a B-Side on her Days/Green single.

PV

The music video for "TO BE" was directed by longtime collaborator Takeishi Wataru. It shows Hamasaki singing as seen by a little boy through a kaleidoscope. It makes use of various backgrounds, outfits, makeup, and wigs to bring as much color as possible into the world the little boy sees. At the end, the kaleidoscope lens breaks, and Hamasaki is seen in black and white.

Alter ego

An alter ego (Latin, "the other I") is a second self, which is believed to be distinct from a person's normal or original personality. A person who has an alter ego is said to lead a double life. The term appeared in common usage in the early 19th century when dissociative identity disorder was first described by psychologists.Cicero was the first to coin the term as part of his philosophical construct in 1st century Rome, but he described it as "a second self, a trusted friend".

A distinct meaning of alter ego can be found in literary analysis, wherein it describes characters in different works who are psychologically similar, or a fictional character whose behavior, speech or thoughts intentionally represent those of the author. It's also used to designate the best friend of another character in a story. Similarly, the term alter ego may be applied to the role or persona taken on by an actor or by other types of performers.

The existence of "another self" was first recognized in the 1730s. Anton Mesmer used hypnosis to separate the alter ego. These experiments showed a behavior pattern that was distinct from the personality of the individual when he was in the waking state compared to when he was under hypnosis. Another character had developed in the altered state of consciousness but in the same body.
