I am a woman because I had two chidren, so I am sure about that. I used to be a medical doctor and a scientist because I publisched article on hystochemistry on journals. So that is sure also. For the rest, I am a human been and live on planet earth, That is sure too. Beside these certainties, I do not know if I ever really existed, as quantum physics say that we are vibrations, ancient mystics say that all is an illusion and so on. Therefore, you decide, I dont care very much. I just enjoy FREEDOM and JOY!
