Pain after death

It is believed that dead people will feel pain long after death, though this might be a conservatively late estimate, but it is scientifically solid.

Organic pain is the body's response to an attack, being a physiological response to harmful stimuli.

Psychological pain is more complex, it is when you think of pain or unpleasant memories, making you feel the pain.

The way one dies can determine the duration of pain one will feel after death. For example, falling 200 feet to one’s death can cause enough pain to last for 3 months while people who died of heart attacks feel little or no pain within one week after death.

Erik Kartman, a Boston Coroner deduced that this could be because the equipment that humans use to sense pain does not close down at once after death and might take some time.

Other than that, it was also believed that the soul will be aware of everything as it leaves the physical body.
