Some years back I read something that made several claims about Islamic bathrooms and conduct within. For instance, toilets could not face toward or away from Mecca. Only the left hand could be used for wiping, and that without the benefit of paper. There were others, but it's been a long time since I read it.
Anyway, I was looking for that when I stumbled upon this item about multicultural medicine. It talks about practices in different cultures involving death and dying, pregnancy and other issues.
