The skin is, for better or worse, an instrument for constructing identity, playfully, through tattoos or piercing, or more painfully, through scarification. By painfully sacrificing a part of oneself, blood, the individual strives to save what is essential. By inflicting a controlled pain on himself, he fights against suffering that is infinitely worse. In order to save the forest, it is necessary to sacrifice one part of it. In the same way, if one is to get on with one’s life, one must sometimes hurt oneself as a way of combating distress.
