Fatigue (medical)
Fatigue (also called exhaustion, tiredness, lethargy, languidness, languor, lassitude, and listlessness) is a state of awareness describing a range of afflictions, usually associated with physical and/or mental weakness, though varying from a general state of lethargy to a specific work-induced burning sensation within one's muscles. Physical fatigue is the inability to continue functioning at the level of one's normal abilities. It is widespread in everyday life, but usually becomes particularly noticeable during heavy exercise. Mental fatigue, on the other hand, rather manifests in somnolence (sleepiness).
Fatigue is a non-specific symptom, which means that it has many possible causes. Fatigue is considered a symptom, as opposed to a medical sign, because it is reported by the patient instead of being observed by others. Fatigue and ‘feelings of fatigue’ are often confused.

Famous quotes containing the word fatigue:
“Croft had an instinctive knowledge of land, sensed the stresses and torsions that had first erupted it, the abrasions of wind and water. The platoon had long ceased to question any direction he took; they knew he would be right as infallibly as sun after darkness or fatigue after a long march.”
—Norman Mailer (b. 1923)
