Sounds like traditional Asian-style laws. You can do the stuff they tell you, you can do, and not anything that isn't detailed. Also, I always wondered why the Hebrew National commercial said they didn't use the rear end of cows, so thank you.

Kosher laws that = a good rule anyway; not having mold on your walls. Though I'd think you'd have to try REALLY HARD to grow mold in the middle east, since it's dry and windy. I knew about not having mixed fibers in your clothing, got any other interesting environment Kosher laws?
