I am not sure how much of this information reaches wider Australia, but I heard on the radio that the teenager who lost his leg to a shark attack in Esperence is Jehovah's witness and his beliefs are impacting on the treatment he can receive for his injury. The media portrayed this as life threatening (which may or may not be true) but I just find it difficult to believe that a person's religious belief about blood (before blood transfusions were even invented!) could result in their incomplete recovery, or death, or worse, the death of a child.
While there are products available that can substitute for blood, there are times when this wont do the job.
Now of course some people would die for their religious beliefs (or as I prefer, values) but still, to refuse treatment for a child? (although in this case I gather it is the teen refusing the treatment, although his belief is based on his family's teachings!)
