Death itself is considered a moment or event rather than a duration. It is the cessation of life and bodily functions. However, the process leading up to death, such as illness or aging, can have a duration. Once death occurs, it is considered a permanent state. **

The duration ends when the specified time period or event has been completed or reached. It could be the end of a specific time frame, the completion of a task, or the occurrence of a particular event. Once the duration has ended, the activity, project, or process associated with it is considered finished or concluded. **

It is important to consult with a healthcare professional before attempting any prolonged fasts to ensure it is safe for your individual health needs. **
