Man Hammers Three Nails In His Head!

Free time leads to boredom, boredom leads to bad decisions, and bad decisions lead to hospital visits. This guy in China either has a pain fetish, owes money to the wrong people, or is the worst carpenter ever.

In what should soon be the worst after school special ever; Dude hammers three nails through his skull, into his brain. Goes to the hospital, has surgery. After a three month recovery, says 'no cops' and leaves (assuming to a hardware store).

I'd like to think this guy has some sort of super power associated with this, otherwise why? And how? This goes against everything I know about not sticking stuff in your brain. If you think you can stomach the pictures and x-rays check them out here.
