Leonardo DaVinci - the man was so far ahead of his time that running n secrecy had to limit him in some way. It would be great to see him have free rein to express his opinions in today's world. Of course, he would still be presecuted becuase some people today still don't get it, but can you imagine what the dude would be like?
I would bring back my Heart. It has been crushed so many times. Shattered into a thousand pieces and burned to the ground. I know you said a person, but it is that which makes me one. I would bring back the heart that did not know pain, that did not know let down and hate. The one that never seen the ugly side of love and fate. That is who I would bring back from the dead. AS the heart I am using now is on borrowed time.
