The Man Who Feels No Pain

Imagine having a giant spike stuck through your face, all the way from mouth to chin, or walking across a bed of broken glass. You'd have to be the ultimate masochist to endure such pain – unless you're Tim Cridland, otherwise known as Zamora, the "Torture King."

Cridland was born without the ability to feel physical pain. Though Cridland believes the strange phenomenon is due to his mental power, researchers who've studied others with the same condition believe that it may be caused by a rare genetic mutation, which prevents the brain from reacting to painful physical stimuli. Unfortunately, the condition doesn't prevent the sort of mental torture promised by Paris Hilton's new reality show. If you think you can take it, check out this video of Zamora's agonizing stage show.
