I have done some research in to what happened when England was invaded. The Scots were the ones who could run the longest and fastest. The Welsh were those who could run and climb, and the Irish were those who could swim. The Southerners were those who could surrender, and the Northerners were those who could fight. It is good theory, anyway. I know a great pie shop in Greenwich, two great fish and chip shops, one in Muswell Hill, and the other in North St, near Euston. All three were founded by missionaries from the North.
