Death is the cessation of all biological functions of living organisms. Common causes of death include aging, predation, malnutrition, disease, suicide, homicide, hunger, dehydration, accidents or major trauma that causes serious injury. In most cases, living organisms begin to decompose shortly after death.

Death - especially human death - is often considered a sad or unpleasant moment because of the deep love for the dead and the termination of social and family ties with the dead. Other problems include fear of death, acrophobia, anxiety, sadness, sadness, emotional pain, depression, compassion, compassion, loneliness, or sadness. Many cultures and religions have the idea of afterlife, as well as the idea of rewarding, judging and punishing past sins.

The concept and symptoms of death, as well as the varying degrees of delicacy used in discussions in public forums, have produced many scientifically, legally and socially acceptable terms or euphemisms. When a person dies, they are also said to have passed away, passed away, expired or disappeared. There are many other socially acceptable, religious specific, linguistic and offensive terms. The dead who lost their lives were corpses, corpses, corpses, wrecks, and all the meat was rotten, bones. The term carrion and car body can also be used, although they usually refer to the remains of non-human animals. Politely mentioning the dead, like the dead, the use of participle form of "the dead" has become a practice. Another noun form is forerunner. The ashes left after cremation are sometimes referred to by the new words "cremains", which means "creation" and "remains".
