Insomnia is a sleep disorder characterized by an inability to sleep and/or to remain asleep for a reasonable period during the night.

Individuals differ from one another in their ability to understand complex ideas, to adapt effectively to the environment, to learn from experience, to engage in various forms of reasoning, to overcome obstacles by taking thought. Although these individual differences can be substantial, they are never entirely consistent: a given person’s intellectual performance will vary on different occasions, in different domains, as judged by different criteria.

Concepts of "intelligence" are attempts to clarify and organize this complex set of phenomena.
