Boredom


Boredom is an emotional state experienced during periods lacking activity or when individuals are uninterested in the opportunities surrounding them. The first record of the word boredom is in the novel Bleak House by Charles Dickens, written in 1852, in which it appears six times, although the expression to be a bore had been used in the sense of "to be tiresome or dull" since 1768.

Sleep



Sleep is a naturally recurring state of relatively suspended sensory and motor activity, characterized by total or partial unconsciousness and the inactivity of nearly all voluntary muscles. It is distinguished from quiet wakefulness by a decreased ability to react to stimuli, and it is more easily reversible than hibernation or coma. It is observed in all mammals, all birds, and many reptiles, amphibians, and fish. In humans, other mammals, and a substantial majority of other animals that have been studied (such as some species of fish, birds, ants, and fruit flies), regular sleep is essential for survival.


The purposes and mechanisms of sleep are only partially clear and are the subject of intense research.
