Final answer:
Max likely is experiencing the stage of resistance, part of the general adaptation syndrome, due to his prolonged lack of sleep.
Step-by-step explanation:
Max hasn't had more than 3 hours of sleep in 2 days. Even though this is true, he feels an abundance of energy like never before. Chances are his body is in the stage of resistance.
The general adaptation syndrome, which explains the body's response to stress, consists of three stages: alarm reaction, stage of resistance, and stage of exhaustion. Initially, during an alarm reaction, the body provides energy to manage the situation which is similar to the fight-or-flight response. If the stress persists, as it likely has for Max due to sleep deprivation, the body then enters the stage of resistance, during which it attempts to adapt to the continuing stressor. Despite feeling energetic, Max's body is likely working hard to maintain this state, which cannot be sustained indefinitely and may eventually lead to the stage of exhaustion if his lack of sleep continues.
