What condition causes people to either want be aggressive or flee?

The condition that causes people to either want to be aggressive or flee is called the "fight or flight" response. This is a natural response to a perceived threat, and it is triggered by the release of hormones such as adrenaline and cortisol. The fight or flight response causes the body to go into a state of high alert, and it increases the person's strength, speed, and agility. This response is designed to help people survive in dangerous situations, and it can be very helpful in the short term. However, if the fight or flight response is activated too often, it can lead to problems such as anxiety, depression, and post-traumatic stress disorder (PTSD).
