Autopsies can be further classified into cases where external examination suffices, and those where the body is dissected and an internal examination is conducted. Permission from next of kin may be required for internal autopsy in some cases. Once an internal autopsy is complete the body is generally reconstituted by sewing it back together. Autopsy is important in a medical environment and may shed light on mistakes and help improve practices. A necropsy, which is not always a medical procedure, was a term previously used to describe an unregulated postmortem examination. In modern times, this term is more commonly associated with the corpses of animals. Senescence
Senescence refers to a scenario when a living being is able to survive all calamities, but eventually dies due to causes relating to old age. Animal and plant cells normally reproduce and function during the whole period of natural existence, but the aging process derives from deterioration of cellular activity and ruination of regular functioning. Aptitude of cells for gradual deterioration and mortality means that cells are naturally sentenced to stable and long-term loss of living capacities, even despite continuing metabolic reactions and viability. In the United Kingdom, for example, nine out of ten of all the deaths that occur on a daily basis relates to senescence, while around the world it accounts for two-thirds of 150,000 deaths that take place daily.Almost all animals who survive external hazards to their biological functioning eventually die from biological aging, known in life sciences as "senescence".
Deaf-mute people in history
The Ottoman Sultans used people referred to as "congenital deaf-mutes" (called in Turkish dilsiz or bizeban, i.e. "mute" or "without tongue") in their own personal service from the 15th century to the end of the Ottoman Empire. Due to their nature, they were often entrusted with confidential and delicate missions, including executions. Deaf-muteness in art and literature
Stephen Kings novel The Stand features a main character named Nick Andros who is referred to as "deaf-mute." Though deaf people almost always have a voice, King interpreted the term literally and made Nick unable to vocalize. However, he could read lips and make himself clearly understood by pantomiming and in writing. The phrase is used in The Catcher in the Rye to indicate someone who does not speak his mind, and hears nothing, in effect becoming isolated from the world. Chief Bromden, in One Flew Over the Cuckoos Nest, is believed by all to be deaf and mute, but in fact he can hear and speak; he does not let anyone know this because, as he grew up, he was not spoken to (making him "deaf") and ignored (making him "mute"). The character Singer in the novel The Heart Is a Lonely Hunter, written in 1940, is referred to as "deaf-mute" throughout. In the classic Zorro stories, television series, etc. Zorros aid Bernardo, a mute, pretends that he can also not hear, in order to get information to aid his master in his fight for justice.
