In general terms, death is defined as the culmination of life, when a person dies his vital signs are null. In medicine, we speak of brain death, when the brain stops working completely and irreversibly, however, for doctors to certify that brain death has occurred, it is necessary to comply with certain procedures, such as the registration of the absence of reflexes in the face of a series of stimuli, and the absolute lack of respiration and to finish taking a flat encephalogram, which reflects the absence of brain activity.
At present, medicine has evolved a lot, allowing the person to continue living artificially, that is, connected to machines that help the heart keep beating. From there arises the modern version of death, such as brain death or irreversible coma, allowing the possibility that these patients, by prior authorization, or by decision of their relatives, can donate their organs to others in need. Death can occur naturally (due to old age or illness); or violently (accidents, suicide, homicide, etc.).
Different religions have their own interpretation of what death means, for example for the Christian religion, death is not the end of life, on the contrary, it is the step towards a new life next to God, death it is the way from the earthly world to heaven, or hell as the case may be. For Muslims, death represents the same as Christianity, the only difference is that they do not have the belief that when they die they will go to hell, since they await the intervention of the prophet Muhammad to save them from condemnation.
In Hinduism, death does not mean going to heaven or hell, they believe that when the person dies, his soul will return through reincarnation, and not necessarily reincarnate in a human body, it is possible that it does in an animal, This will depend on the Karma and the performance of the person in his old life.
Traditionally, the image of death is personified by a skeletal female figure dressed in black and carrying a sickle in her hand.
