It is the time lapse between death and discovery. After death, decomposition occurs. Decomposition includes physical, chemical, and biological changes. [19] Below are some of the biochemical changes that happen during decomposition which can help estimate the time since death (keeping in mind that there is variation between species): [20]
Conversely, premature death can refer to a death that occurs before old age arrives, for example, human death before a person reaches the age of 75. [78] Animal and plant cells normally reproduce and function during the whole period of natural existence, but the aging process derives from the deterioration of cellular activity and the ruination ...

One definition of death anxiety is a "feeling of dread, apprehension or solicitude (anxiety) when one thinks of the process of dying, or ceasing to 'be'". Also known as thanatophobia (fear of death).

A fresh pig carcass. At this stage the remains are usually intact and free of insects. The corpse progresses through algor mortis (a reduction in body temperature until ambient temperature is reached), rigor mortis (the temporary stiffening of the limbs due to chemical changes in the muscles), and livor mortis (pooling of the blood on the side of the body that is closest to the ground).
Saying goodbye to Kate before she left her physical body — on her own terms, just as she wanted. Kate knew what she had and how severe it was. During the almost two years she lived with ...
It is now understood that death is a series of physical events, not a single one, and determination of permanent death is dependent on other factors beyond simple cessation of breathing and heartbeat. [11] Clinical death that occurs unexpectedly is treated as a medical emergency. CPR is initiated.
Rigor mortis [a] (from Latin rigor 'stiffness' and mortis 'of death'), or postmortem rigidity, is the fourth stage of death.It is one of the recognizable signs of death, characterized by stiffening of the limbs of the corpse caused by chemical changes in the muscles postmortem (mainly calcium). [1]
