There are only 7% of people in the world practice infant circumcisions . The remainders who have done circumcision (about 13%) practice childhood/teenager circumcisions But percentage of circumcised infant who become a Nobel Prize Winner is about 8-9 times higher. Yes, percentage of Nobel Prize Winners among circumcised men are much more than uncuts. Does infant circumcision increasing probability of genius people? Is it true when a baby was circumcised his body produce a special chemical/hormone that influent his brain growth and make him have a better probability to be more intelligent ? Looking at the Jews ...it does work. I challenge you all of researchers to make a scientific study about it.
