@synapse.files: The millisecond an acute threat is registered, your sympathetic nervous system initiates a total neurological override. Your prefrontal cortex undergoes transient hypofrontality stripping away rational overthinking while descending spinal pathways release endogenous opioids to physically silence pain receptors. If the circulating epinephrine is not burned off through immediate physical exertion, your motor units discharge the unspent glucose through neurogenic tremors.
