I disagree. Smashing your face with a hammer is simply pretty damn harmful. There's just no believing or disbelieving this one. Anyone who smashes their face with a hammer isn't doing it because they don't see it as harmful (unless of course they've taken enough Vicoden that they're about to be dead anyway). They're doing it because they want to be harmed. Big difference.
Sometimes hitting yourself with a hammer can be a good thing. It depends on what you know and how it is being applied. For example, when your treating your head as a nail and coming at is a doctor who specializes in the treatment of acne, your likely to get fairer skin. The only reason the hammer is harmful in this case is because he isn't using the right hammer for the job.
