Chronic fatigue sounds rough, it brings long term fatigue and limits a person to carry out daily things.
Chronic fatigue syndrome (CFS), also referred to as myalgic encephalomyelitis (ME), is a medical condition characterized by long-term fatigue and other symptoms that limit a person's ability to carry out ordinary daily activities.

Chronic fatigue syndrome
Chronic fatigue syndrome (CFS), also referred to as myalgic encephalomyelitis (ME), is a medical condition characterized by long-term fatigue and other symptoms that limit a person's ability to carry out ordinary daily activities. Biological, genetic, infectious, and psychological mechanisms have been proposed, but the cause is not understood. Diagnosis is based on a person's symptoms. The fatigue is not due to strenuous ongoing exertion, is not much relieved by rest, and is not due to a previous medical condition. Fatigue is a common symptom in many illnesses, but the unexplained fatigue and severity of functional impairment in CFS is comparatively rare.
Cancer-related fatigue
Cancer-related fatigue is a subjective symptom of fatigue that is experienced by nearly all cancer patients. Among patients receiving cancer treatment other than surgery, it is essentially universal. Fatigue is a normal and expected side effect of most forms of chemotherapy, radiation therapy, and biotherapy. On average, cancer-related fatigue is "more severe, more distressing, and less likely to be relieved by rest" than fatigue experienced by healthy people. It can range from mild to severe, and may be either temporary or a long-term effect. Fatigue may be a symptom of the cancer, or it may be the result of treatments for the cancer.
History of chronic fatigue syndrome
The history of chronic fatigue syndrome (CFS, also known by many other names) is thought to date back to the 19th century and before. Several descriptions of illness resembling those of chronic fatigue syndrome have been reported for at least two hundred years. In the 19th century, neurologist George Miller Beard popularised the concept of neurasthenia, with symptoms including fatigue, anxiety, headache, impotence, neuralgia and depression. This concept remained popular well into the 20th century, eventually coming to be seen as a behavioural rather than physical condition, with a diagnosis that excluded postviral syndromes.
Chronic fatigue syndrome treatment
Treatment of chronic fatigue syndrome (CFS) is variable and uncertain, and the condition is primarily managed rather than cured. Only two treatments, cognitive behavioral therapy and graded exercise therapy, have demonstrated reproducible evidence for their efficacy people with CFS who are walking. There are no Food and Drug Administration (FDA) approved medications for ME/CFS treatment, although medications are used without approval for the illness (off-label). Drugs have been used in experimental studies of the illness that haven't been approved for market for any condition in the United States (for example, isoprinosine and rintatolimod).
Clinical descriptions of chronic fatigue syndrome
The clinical descriptions of chronic fatigue syndrome (CFS) vary. Different agencies and scientific bodies have produced different guidelines to define the condition, with some overlap of symptoms between descriptions. Aspects of the condition are controversial, with disagreements over etiology, pathophysiology, treatment and naming between medical practitioners, researchers, patients and advocacy groups. Subgroup analysis suggests that, depending on the applied definition, the CFS population may represent a variety of conditions rather than a single disease entity. The most widely used diagnostic criteria for CFS are the 1994 research guidelines proposed by the "International Chronic Fatigue Syndrome Study Group", led by the Centers for Disease Control and Prevention.
Fibromyalgia
Fibromyalgia (FM) is a medical condition characterised by chronic widespread pain and a heightened pain response to pressure. Other symptoms include tiredness to a degree that normal activities are affected, sleep problems, and troubles with memory. Some people also report restless legs syndrome, bowel or bladder problems, numbness and tingling, and sensitivity to noise, lights or temperature. Fibromyalgia is frequently associated with depression, anxiety, and posttraumatic stress disorder. Other types of chronic pain are also frequently present. The cause of fibromyalgia is unknown; however, it is believed to involve a combination of genetic and environmental factors with half the risk attributed to each.
Central nervous system fatigue
Central nervous system fatigue, or central fatigue, is a form of fatigue that is associated with changes in the synaptic concentration of neurotransmitters within the central nervous system (CNS; including the brain and spinal cord) which affects exercise performance and muscle function and cannot be explained by peripheral factors that affect muscle function. In healthy individuals, central fatigue can occur from prolonged exercise and is associated with neurochemical changes in the brain, primarily involving serotonin (5-HT), noradrenaline, and dopamine. Central fatigue plays an important role in endurance sports and also highlights the importance of proper nutrition in endurance athletes.

That sound miserable.  What causes chronic fatigue?

What is scary is they do not know the exact cause, its not even genetic or biological.
Biological, genetic, infectious, and psychological mechanisms have been proposed, but the cause is not understood.

Tourette syndrome
Tourette syndrome (TS or simply Tourette's) is a common neuropsychiatric disorder with onset in childhood, characterized by multiple motor tics and at least one vocal (phonic) tic. These tics characteristically wax and wane, can be suppressed temporarily, and are typically preceded by an unwanted urge or sensation in the affected muscles. Some common tics are eye blinking, coughing, throat clearing, sniffing, and facial movements. Tourette's does not adversely affect intelligence or life expectancy. Tourette's is defined as part of a spectrum of tic disorders, which includes provisional, transient and persistent (chronic) tics.
Race and intelligence
The connection between race and intelligence has been a subject of debate in both popular science and academic research since the inception of IQ testing in the early 20th century. While tests have broadly shown differences in average scores based on self-identified race or ethnicity, there is considerable debate as to whether and to what extent those differences reflect environmental factors as opposed to genetic ones, as well as to the definitions of what "race" and "intelligence" are, and whether they can be objectively defined at all. Currently, there is no non-circumstantial evidence that these differences in test scores have a genetic component, although some researchers believe that the existing circumstantial evidence makes it at least plausible that hard evidence for a genetic component will eventually be found.
Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. Evolutionary processes give rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. Repeated formation of new species (speciation), change within species (anagenesis), and loss of species (extinction) throughout the evolutionary history of life on Earth are demonstrated by shared sets of morphological and biochemical traits, including shared DNA sequences. These shared traits are more similar among species that share a more recent common ancestor, and can be used to reconstruct a biological "tree of life" based on evolutionary relationships (phylogenetics), using both existing species and fossils.
Race (human categorization)
Race is a concept used in the categorization of humans into groups, called races or racial groups, based on combinations of shared physical traits, ancestry, genetics, and social or cultural traits. Although such groupings lack a firm basis in modern biology, they continue to have a strong influence over contemporary social relations. First used to refer to speakers of a common language and then to denote national affiliations, by the 17th century race began to refer to physical (phenotypical) traits. The term was often used in a general biological taxonomic sense, starting from the 19th century, to denote genetically differentiated human populations defined by phenotype.
Dual inheritance theory
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. Genes and culture continually interact in a feedback loop, changes in genes can lead to changes in culture which can then influence genetic selection, and vice versa. One of the theory's central claims is that culture evolves partly through a Darwinian selection process, which dual inheritance theorists often describe by analogy to genetic evolution.
Dingo–dog hybrid
A dingo–dog hybrid is a cross between a dingo and a domestic dog. The current population of free ranging domestic dogs in Australia is now probably higher than in the past. However, the proportion of the so-called "pure" dingoes (dogs with exclusively dingo-ancestry) has been in the decrease over the last few decades due to hybridisation and is regarded as further decreasing. Because of this ongoing interbreeding of dingoes and other domestic dogs and the resulting hybrids, there is a much wider range of colours and body shapes today among the Australian wild dog population than in the time before the human introduction of domestic dogs.
Cousin marriage
Cousin marriage is marriage between cousins (i.e. people with common grandparents or people who share other fairly recent ancestors). Opinions and practice vary widely across the world. In some cultures and communities, cousin marriage is considered ideal and actively encouraged; in others, it is subject to social stigma. Cousin marriage is common in the Middle East, for instance, where it accounts for over half of all marriages in some countries. In some countries outside that region, it is uncommon but still legal. In others, it is seen as incestuous and is legally prohibited: it is banned in China and Taiwan, North Korea, South Korea, the Philippines and 24 of the 50 United States.

Interesting.  Is it more common in children or adults?
