When were you first you?

When did you come into existence? At conception. At implantation. When my heart first started beating. When I first had brain waves. When all of my organs were fully formed. When I started making purposeful movements. When I became capable of responding to my environment. When I became able to distinguish between "self" and "other". When I first was able to deliberately communicate with another person. I'm constantly evolving, so the question has no meaning; the "me" I am now is different from the "me" of yesterday.    Free polls from Pollhost.com
