Fight-or-fight response

Explanation:

Fight-or-fight response :

The fight or-flight reaction, otherwise called the intense pressure reaction, alludes to a physiological response that happens within the sight of something that is frightening, either rationally or physically. The reaction is activated by the arrival of hormones that set up your body to either remain and manage a danger or to flee to security.

It represents the decisions that our antiquated precursors had when looked with peril in their condition. They could either battle or escape. In either case, the physiological and mental reaction to stretch readies the body to respond to the threat.
