National Geographic's Taboo series looks at gaming and internet addiction in South Korea in tonight's episode, focusing on a "15-year-old South Korean boy in rehab because he's hooked on video games."

The National Geographic Channel touches on the struggle of teenager Hung Gu, who attends the Internet Rescue School's rehab program. NatGeo's story on South Korea's "gaming epidemic" is tied with other unusual addictions like a California woman's addiction to anonymous sex—"meeting countless partners in parking lots to satisfy her insatiable appetite"—and an Australian who has shopped himself into $100,000 in debt.

Taboo airs on the National Geographic Channel tonight, Monday, May 9, 2011, at 10 PM ET/PT.
