- - - - • Planning
      - • Diagnosis
      - • Rehearsing
  - - - always exhausted
      - unmanageable
      - constantly irritated
- - - - Role of fatigue becomes significant in long term operations
      - Truck and bus drivers, operators and etc.
    - - Degrade performance :arrow_double_down:
      - Buildup of fatigue :tired_face:
      - prolong period of performance without rest :sleepy:
    - - A state of muscle & the central nervous system. 🦾🧠🦿
      - Prolonged physical activity/mental processing
      - Not enough rest and don't have energy to do work 😪
    - - degrades performance :frowning_face:
      - create problems in maintaining attention :!!:
  - - - Duration of watches.
      - Signal enchancement
      - .
      - Alter criterion for detecting signals,changing signal expectancy
    - - Time :clock2:
        
        :black_small_square: Longer time, greater likelohood of error
      - Event Salience
        
        :black_small_square: Bright, loud --- easy to detect
        
        :black_small_square: Event that is subtle
