i agree that to each his own in terms of what they do with their bodies...
but at the same time, a lot of these things are a "trend" and could lead to regrets e.g. the man who tatooed a big mural of his wife and family on his back, but she left im for his best mate two weeks later or something, now he's stuck with the thing...
things like branding are with you for life and it should not be a decision taken lightly, something that looks cool in the moment might turn out to be a regret in the long run... so think about it!!! especially the amputation thing, to me that doesn't make sense, did anyone watch that program about voluntary eunuchs a lil while back... jeeeez
