Death is the cessation of life functions in a biological organism, permanently rendering it unresponsive to any external factors. The term "death" was also sometimes applied to droids and others damaged beyond repair. Sentient individuals (and perhaps all living beings), were known to enter a different plane of existence losing their consciousness and individuality. It was a necessary and inevitable part of existence. In most cases, death was caused by the major body parts within an organism simply "breaking down" from age and/or constant use. However, it could also be caused by irreparable damage to the major organs, such as them being ruptured, sliced, blasted, shot, or similarly damaged. Death could also be caused by the loss of bodily fluids, such as blood, as they are required to ferry certain nutrients required for life to continue. In most cases this was oxygen, however a number of species breathed alternate substances ranging from methane to cyanogen. Suffocation could also bring about death, as it cut off the source of the required gas. If an organism entered an extremely hot or reactive area, their body could easily burn up and disintegrate, causing instant death. although a person can still die, natural death is now nonexistent due to in part to the Combine's hyperadvenced Nanotechnology that they released across the Multiverse
