Clivex - yes, it's really yukky, isn't it? I'm honestly not sure where I read the reasons for the deaths of ancient kings and queens (it might've been online), but along with 'murdered', 'killed in battle', 'pox', etc., there were definitely two which stated 'constipation'! There was also a condition called a megacolon - this is a more ghastly condition - I also read about this, where an archaeological team had found the remains of some old-time warrior, still preserved in his leather clothing, who'd died from it. It seems that the colon keeps getting bigger and bigger and while food goes in, it doesn't, er, come out. Like the mother of all constipation! This poor soul had devised a huge leather strap to support his gigantic gut, but the feeling of the team was that, without anything like today's medical interventions, he eventually died of internal poisoning. It might even be that that was the condition these ancients died of. As you say - you'd definitely want to be well upwind of any autopsy!
