However, she did not mention a source for the statement nor identify its position in relation to other top reasons.In 2011, the South Korean government implemented a law, known as the Shutdown law or the Cinderella Law, which prohibits children under the age of 16 from playing online video games between the hours of 12:00 a.m. to 6:00 a.m. Later on, the law was amended and now children under the age of 16 can play after midnight if they have permission from their parents. In 2021, the South Korean government moved to abolish this law.A systematic review identified in 2017 three types of currently attempted governmental policies: 1) limiting the availability of video games (shutdown, fatigue system, parental controls),  2) reduce the risks and harm (warning messages), 3) provide addiction help services to gamers. Most of these policies were either not as efficient as intended or not yet evaluated for efficiency, which lead some researchers to prompt for a global public health approach to prevent the onset and progression of this disorder. Some researchers suggest that the video game industry should itself place preventive measures against video game addiction. Deaths
There have been at least a few deaths caused directly by exhaustion from playing games for excessive periods of time. China
In 2005, thirteen-year-old Zhang Xiaoyi committed suicide by jumping from the top of a 24-story tower block in his home province Tianjin.
Hypoventilation in COPD involves multiple mechanisms, including decreased responsiveness to hypoxia and hypercapnia, increased ventilation-perfusion mismatch leading to increased dead space ventilation, and decreased diaphragm function secondary to fatigue and hyperinflation. Chronic respiratory acidosis also may be secondary to obesity hypoventilation syndrome (i.e., Pickwickian syndrome), neuromuscular disorders such as amyotrophic lateral sclerosis, and severe restrictive ventilatory defects as observed in interstitial lung disease and thoracic deformities. Lung diseases that primarily cause abnormality in alveolar gas exchange usually do not cause hypoventilation but tend to cause stimulation of ventilation and hypocapnia secondary to hypoxia. Hypercapnia only occurs if severe disease or respiratory muscle fatigue occurs. Physiological response
Mechanism
Metabolism rapidly generates a large quantity of volatile acid (H2CO3) and nonvolatile acid. The metabolism of fats and carbohydrates leads to the formation of a large amount of CO2. The CO2 combines with H2O to form carbonic acid (H2CO3). The lungs normally excrete the volatile fraction through ventilation, and acid accumulation does not occur. A significant alteration in ventilation that affects elimination of CO2 can cause a respiratory acid-base disorder. The PaCO2 is maintained within a range of 35–45 mm Hg in normal states. Alveolar ventilation is under the control of the respiratory center, which is located in the pons and the medulla. Ventilation is influenced and regulated by chemoreceptors for PaCO2, PaO2, and pH located in the brainstem, and in the aortic and carotid bodies as well as by neural impulses from lung stretch receptors and impulses from the cerebral cortex. Failure of ventilation quickly increases the PaCO2.
