Dozens of citizens take part in Seoul's "space-out" competition in which participants are required to sit idly without talking, sleeping, eating, or using any electronic devices, at a riverside park in Seoul on May 22, 2016.
The competition has gained popularity in South Korea since local artists organised the first edition in Seoul in 2014 as a satire of modern life dominated by social media and smartphones. / AFP / JUNG YEON-JE        (Photo credit should read JUNG YEON-JE/AFP/Getty Images)
