second phase of GAS. the body adapts to its high state of arousal as it tries to cope with the stressor. continuing to draw on resources of fat and muscle, it shuts down unnecessary processes: digestion, growth, and more. the body is being taxes to generate resistance, and all the fun stuff is put on hold.
third phase of GAS the boy's resistance collapses. many os the resistance-phase defenses create gradual damage as they operate, leading to costs for the body that can include susceptibility to infection, tumor growth, aging, irreversible organ damage, or death.
