Imagine a zebra on the savannah, where the most stressful event will be to flee from a lion for survival. Once the immediate danger has passed, it will settle and calm down quickly. Humans, on the other hand, can remain traumatized by imagining and ruminating on what might have happened. Our capacity to anticipate, imagine, or ruminate can stimulate the threat system continuously, leading to effects that are detrimental to both our physical and mental health.
-Agnes M.F. Wong
