“Normal” is a word that is relative to time and space. I always reserve a special place in my heart for those who are called “freaks” and their care takers. Those “abnormal” persons are just the victims of chance. In case of CFC, it is so rare, and actually he was really “lucky” (one in a billion chance?) to have it.
I wish that everyone knew a little bit about genetics, so we will have a better understanding what “abnormal” actually is, and how lucky we are to be "normal".
