I've sat in the oncology ward at the Royal Melbourne Hospital for a solid six months and watched scores of patients undergoing the most diabolical treatments anybody could ever conceive. People so blasted by the chemotherapy drugs that they can't even be visited, lest their damaged immune system succumbs to even the weakest of infections. I sat with someone as they dripped blood because there was a severe shortage of platelets and they had none of their own to clot with.
If there was a better solution, we'd be using it.
