Digital technology in the form of mobile phones and computers is shaping people's lives around the world.
Lee Ji Hoon, 24, is a professional game player living in Seoul.
"I practice over six hours a day, until 3am to keep up my skills on PC football. I like to play people on the internet, and sometimes compete with players outside Korea.
"When I get stressed out or tired of playing on the PC, I play other computer games or watch movies over the net. There isn't much to do other than staying online here. It's designed that way."
