Honey and Hand Grenades

For years I was a hero. Cure a worldwide epidemic, people tend to think highly of you. Pharmaceutical companies didn't see it that way. No good deed goes unpunished. Profits declining. They tried to eliminate me. Years away, reinventing myself. Now I'm back. New identity, the target on my back remains. I'd tell you my name, but it changes every day. Call me whatever you like, it's irrelevant. Names simply words after all. Actions speak volumes anyway. And my actions might just be more than anyone is prepared to handle.
