As you will probably know, Jewish people practice ritual mutilation on their young boys on the eighth day from birth. Apart from this, Australia, Japan, America and Canada are regions where circumcision was almost automatic until fairly recently.
In Britain, according to some rather odd research carried out by a mate at University in the 1960s, 15% of males are circumcised, with an increasing rate with age. This was explained as a cultural fashion that has since died out.
Let us hope that this also dies out in those other countries too.
