A human skull, widely used as a symbol of death and decomposition

Death is the termination of all biological functions that sustain a living organism. Phenomena which commonly bring about death include biological aging (senescence), predation, malnutrition, disease, suicide, homicide, starvation, dehydration, and accidents or trauma resulting in terminal injury.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Bodies of living organisms begin to decompose shortly after death. Death of humans has commonly been considered a sad or unpleasant occasion, due to the termination of bonds with or affection for the being that has died, or having fear of death, necrophobia, anxiety, sorrow, grief, emotional pain, depression, sympathy, compassion, solitude, or saudade.
