Sorry East Anglia - the high ranking doctor (probably a geneticist) had to apologise for pointing this out. He did not apologise for the truth of it - citing Norfolk in particular. And as he said - the term inbreeding is the correct technical term but encompasses a wider concept than the public have of it - hence the umbrage.

And just to even up the umbrage dare I repeat an old newspaper headline - well quoted -

"Incest more common than thought in America"

ducks and runs for cover.
