We have all experienced stress and its adverse effects.  Stress might be seen as a wrench which is thrown into a well functioning, yet complex, mechanical device—in this case your mind, causing that device to seize by wreaking havoc on the device’s inner architecture and severely impairing its structural components. Although the damage is not irreparable—after removing the wrench, the machine’s various damaged cogs, belts, and levers can be replaced—damage has nonetheless been done, and the cleanup effort no doubt would be painstaking. For students, stress—given its harmful psycho-physiological (i.e. psychosomatic) effects—can be especially menacing.
