The sense of fatigue is believed to originate in the reticular activating system of the lower brain. Musculoskeletal structures may have co-evolved with appropriate brain structures so that the complete unit functions together in a constructive and adaptive fashion. The entire systems of muscles, joints, and proprioceptive and kinesthetic functions plus parts of the brain evolve and function together in a unitary way.

“The perception of the comic is a tie of sympathy with other men, a pledge of sanity, and a protection from those perverse tendencies and gloomy insanities in which fine intellects sometimes lose themselves. A rogue alive to the ludicrous is still convertible. If that sense is lost, his fellow-men can do little for him.”

“Men are not philosophers, but are rather very foolish children, who, by reason of their partiality, see everything in the most absurd manner, and are the victims at all times of the nearest object. There is even no philosopher who is a philosopher at all times. Our experience, our perception is conditioned by the need to acquire in parts and in succession, that is, with every truth a certain falsehood.”
—Ralph Waldo Emerson (1803–1882)
“I have just read your dispatch about sore tongued and fatiegued [sic] horses. Will you pardon me for asking what the horses of your army have done since the battle of Antietem that fatigue anything?”
—Abraham Lincoln (1809–1865)
