Now, that makes sense in a situation where you're fighting an attacker or a mountain lion. However, in the modern world, where do we see this happening most frequently? We're not really in many situations where we actually physically need to make a decision to fight somebody or to flee, okay? In certain instances yes that is the case but in general, where this - this - um - mechanism of the brain is activating and going to work most frequently is when we are engaged in stressful activities. And we're almost always engaged in stressful activities, particularly in western cultural - uh - life. So. Unfortunately this places us at an even greater disadvantage. This is actually an advantageous survival adaption technique in the brain, which has become a detriment in modern society.
