"Yeah, babe, I'm a bounty hunter"
Just don't follow it up with "... just like Boba Fett"
good comment, however
DNA carries much more information about a person. As technologies improve in the genetics industry and with human ingenuity for dastardly deeds, it's not hard to conceive of how this information could be abused.
Once you're in the system, there's usually no way out. Be very cautious about things with things that can't be undone.
