No. Dr. Z. is not some reincarnate of Dr. Zhivago nor is he the much beloved Dr. Z. of the Chryler commercials.
Because of the fate of Joan of Arc and because of the constant threat of capture from Burgundian troops Dr. Z’s identity must remain anonymous, at least until his first book is published or someone is willing to pay him $50 to come and speak to a 4H-Club leadership jamboree.
Perhaps Dr. Z’s identify is superfluous, and don’t say that with your mouth full of dental implements.
If you are searching for Dr. Z’s identify you are looking in the wrong direction. Follow the advice given to Simba in the Lion King:
You have forgotten who you are and so have forgotten me. Look inside yourself, Simba. You are more than what you have become. You must take your place in the Circle of Life
Or at least take your place in line for a beer and a hot dog at the baseball game before you miss the 8th inning.
