Self preservation
Introduction
Self preservation is part of an animal‘s instinct that demands that the organism survives. Pain and fear are parts of this mechanism. Pain causes discomfort so that the organism is inclined to stop the pain. Fear causes the organism to seek safety and may cause a release of adrenaline which has the effect of increased strength and heightened senses such as hearing, smell, and sight.
