Exformation is a term related to information for describing useful and relevant information or a specific kind of information explosion. With exformation, thought is in fact a process of throwing away information, and it is this detritus that is crucially involved in automatic behaviours of expertise such as riding a bicycle or playing the piano.

In using words, sounds and gestures, a speaker has deliberately thrown away a huge body of information, though it remains implied. Exformation is everything we do not actually say but have in our heads when, or before, we say anything at all. Information is the measurable, demonstrable utterance we actually come out with.

If someone is talking about cows, what is said will be unintelligible unless the person listening has some prior idea what a cow is, what it is good for, and in what context one might encounter one. From the information content of a message alone, there is no way of measuring how much exformation it contains.

In 1862 the author Victor Hugo wrote to his publisher asking how his most recent book, Les Misérables, was doing. Hugo wrote “?” in his message, to which his publisher replied “!”, to indicate it was selling well. This exchange of messages would have no meaning to a third party because the shared context is unique to those taking part in it. The amount of information was extremely small, and yet because of exformation a great deal of meaning was clearly conveyed.



The Belted Kingfisher is a stocky, medium-sized bird with a large head and a shaggy crest. Its long, heavy bill is black with a grey base. Both sexes have a slate blue head, large white collar, a large blue band on the breast, and white underparts.

It is often seen perched prominently on trees, posts, or other suitable watchpoints close to water before plunging in head first after fish. It also eat amphibians, small crustaceans, insects, small mammals and reptiles.

The Belted Kingfisher migrates from the northern parts of their range to the southern United States and Central America in winter. In warmer areas it is a permanent resident. It frequently announces its presence with a loud rattling cry.

The breeding distribution of the Belted Kingfisher is limited in some areas by the availability of suitable nesting sites. Human activity, such as road building and digging gravel pits, has created banks where kingfishers can nest and allowed the expansion of the breeding range.


Eustress is a term coined by endocrinologist Hans Selye, who performed important scientific work on the hypothetical response of an organism to stressors. It is defined as stress that is healthy or gives one a feeling of fulfillment or other positive feelings. Eustress is a process of exploring potential gains.

Distress, with its negative implications, is the most commonly referred to type of stress, whereas eustress is a positive form of stress usually related to desirable events in a person’s life. Both can be equally taxing on the body and are cumulative in nature depending on a person’s way of adapting to a change that has caused it.

Eustress can be defined as a pleasant or curative stress. Just as there are many stressful situations that can lead to the development of depression, anxiety and apathy, there are also types of eustress that promote general emotional and physical well being.

There are many examples of eustress that many people encounter throughout their lives. All of them ultimately provide some degree of happiness and well being. Graduating from high school or college, the birth of children or securing a highly desirable job are all events that come with some amount of stress but ultimately provide positive emotions that help people to find meaning and value in life.
