So, here is the thing about adrenaline.

Adrenaline can save your life. It is a production of nature intended to help us survive. When our brain recognizes a situation that could be dangerous to us in any way, it pops off a squad of hormones from the adrenal gland that prepares the body to save itself. Whether we need to run five miles,lift a car, or fight off a bear, our body prepares itself when these warrior hormones pulse out into our bloodstream. It heightens and increases our blood circulation, breathing, and carbohydrate metabolism and gets muscles amped for exertion.
