Death
Death represents the ultimate boundary of life, marking the irreversible end of an organism's biological processes. This fundamental phenomenon shapes human experience, culture, and understanding of existence.
Biological Definition
From a scientific perspective, death occurs when:
- Cessation of heart function becomes permanent
- brain death occurs, with no electrical activity
