I was watching a prog on the battle of Thermopylae. The Spartans who formed the spearhead - and who were doomed - all had male kids and so had done their bit for Sparta. The Swiss, of course, have their militia, and you only have to go back to the early 20th century to uncover a cultural expectation that citizens might have to fight. So............if we were a rational society we'd have a bloody big sign at Dover that said, "Welcome to Sparta". Every adult male would be (legally and culturally) obliged to stay fit and trained, and if we had to fight we'd send the 35-40 year olds first, then 40-50, and only then below thirty. By the time you've hit 35 you've at least had a "go". Most men would rather fight than see their sons fight. ...and I know it ain't going to happen. Because we're an island over-run by selfish lazy c*nts [It's that kind of Sunday, I fear].
