Of course he’s got into trouble for saying this:

Dr Ian Gibson, the Norwich North MP and former
chairman of the Commons science and technology committee, proposed
inbreeding as a reason for the high incidence of diabetes among
children in the area.

"I
would imagine it is linked to the fact that people in Norfolk are quite
inbred, with many not leaving the county," he told the Eastern Daily
Press this week.

Cue jokes about rural practices at this point. But his actual point:

"I am not talking about incest," he said. "But people in past generations did not move around so much.

"Norfolk people are really no different to those in other areas of the
country. You find populations with a high incidence of illnesses like
sickle cell anaemia.

"My purpose in bringing this
up is not to denigrate anyone but to try to understand why there is a
high rate of diabetes among children in Norfolk."

The incidence of Type 1 diabetes among children in Norfolk is almost twice the national average.

Which leads me to one of my favourite stories, one which you may well have seen here before. The possibly (probably?) apocryphal geneticist when asked which single invention did the most for the health of the working countryman answered:

"The bicycle. It allowed them to court outside the village".
