Proof of Apocalypse: Excited Delirium

Wikipedia: "Excited delirium is a condition that manifests as a combination of delirium, psychomotor agitation, anxiety, hallucinations, speech disturbances, disorientation, violent and bizarre behavior, insensitivity to pain, elevated body temperature, and superhuman strength.[1][2] Excited delirium is sometimes called excited delirium syndrome if it results in sudden death (usually via cardiac or respiratory arrest), an outcome that is sometimes associated with the use of physical control measures, including police restraint and tasers.[1][2] Excited delirium arises most commonly in male subjects with a history of serious mental illness and/or acute or chronic drug abuse, particularly stimulant drugs such as cocaine.[1][3] Alcohol withdrawal or head trauma may also contribute to the condition."
