The Fight or Flight Response.
The stress is reaction of body.
Stress hormones can focus concentration and speed reaction time.
The principle stress is a maximum tension stress in a body where shear stress is zero and it acts on the principle plane. If a body is under both tension and shear then the principle stress is higher than the initial tension stress. You can calculate this and find the principle plane angle using Mohr Circle analysis or equations.

An initial reaction to something alarming would be the alarm stage. This is when the adrenaline courses through the body. The resistance stage comes after the alarm stage, and this is when the body repairs any damage to the system that had been caused by the alarm stage.
General adaptation syndrome, or GAS, is a term used to describe the body's short-term and long-term reactions to stress. There are three stages the alarm reaction, the stage of resistance, and the stage of exhaustion.
