The adrenals are two small glands that sit one on top of each kidney. These tiny glands are related to stress and our “fight or flight” response. The fight or flight response is designed to keep us alive at all costs! This stress response was modeled to keep energy flowing to the muscles and the brain for pure basic survival.
Do or die is the overwhelming drive behind the body’s reaction to a stressor! So you can see that the stress response has evolved over thousands of years to be the very strong and effective deterrent to death! Now there is no more wondering why stress can be so detrimental. Especially when the stress is a result of something non-death-threatening like a deadline or a defiant teenager!
