But your attention is focused, your vision becomes crystal clear

As soon as the stressful event occurs, it triggers the release of the cascade of hypothalamic, pituitary, and adrenal hormones — the brain’s stress response. It also triggers the adrenal glands to release epinephrine, or adrenaline, and the sympathetic nerves to squirt out the adrenaline-like chemical norepinephrine all over the body: nerves that wire the heart, and gut, and skin. So, the heart is driven to beat faster, the fine hairs of your skin stand up, you sweat, you may feel nausea or the urge to defecate. But your attention is focused, your vision becomes crystal clear, a surge of power helps you run — these same chemicals released from nerves make blood flow to your muscles, preparing you to sprint.

  4. I suppose it means we shouldn’t sweat the big stuff — or the little stuff — don’t wanna throw up or anything —

  5. Ah, the science behind the “Fight or Flight” response to danger. As it also is in the animal world. The difference is, in the animal world, the threat is always a reality.
