I think kid smartphone addiction is real problem. A recent study surveyed almost 1,000 students in South Korea, where 72% of children own a smartphone by the age of 11 or 12 and spend on average 5.4 hours a day on them - as a result about 25% of children were considered addicted to smartphones. The study, to be published in 2016 found that stress was an important indicator of your likelihood to get addicted.
Smartphones are central to many societies but they have been integrated into Asian cultures in many ways: there is the obligatory "food porn" photograph at the beginning of any meal; in Japan it is an entire subculture with its own name - keitai culture.
Asia and its 2.5bn smartphone users provides a stream of phone-related "mishap news", such as the Taiwanese tourist who had to be rescued after she walked off a pier while checking Facebook on her phone. Or the woman from China's Sichuan province rescued by fire fighters after falling into a drain while looking at her phone.
They may make for slapstick headlines but in Singapore too the concern is that those most vulnerable are getting younger. With its population of just 6 million, it has one of the world's highest smartphone penetration rates. It also has specialists in digital addiction, a cyber wellness clinic and a campaign to see digital addiction be formally recognised.
