death

Death is the permanent cessation of all biological functions that sustain a living organism. It marks the end of life and can occur due to various factors, including aging, illness, or injury. In humans, it is commonly understood as the point when the heart stops beating and the brain ceases to function. Culturally and emotionally, death can evoke a range of responses, often involving grief for those left behind. It is a natural part of the life cycle and raises important questions about existence, meaning, and what may, if anything, come after life.
