Re DDW, exactly. And most of the Jewish rituals (not eating the meat of scavenging animals like pork, and circumcision) make a lot of sense when you consider that they were thought up during a long period spent as nomads. It you're constantly on the move, the last thing you want is food poisoning or illness, otherwise you'll either slow up the whole company or be left behind when the group moves on. It just seems that someone forgot to tell them to stop when they settled...

Grab.
